"Twenty years ago I first saw the Hebrew Bible appear on my computer screen. Since that time Bible software has matured from a curiosity to a necessity, and Accordance is clearly the best of the bunch. Whether primary texts, reference tools, or secondary studies, they are now on the hard drive of my laptop and accompany me from my study, into the classroom, on my travels, and even to my phoneless, email-less, backwoods cabin. A library full of resource materials, many of which were difficult to find in all but the very best research libraries, is ready to aid my curiosity as I seek to understand the ancient cultures and texts that are the focus of the Biblical Studies student."

"For biblical scholars and students who are Mac users, there is no need to look further than the constantly evolving and resolutely powerful Accordance Bible Software from OakTree software.

I have used this product since its inception. It continues to move from strength to strength, providing simple and complex search resources for biblical texts in Hebrew, Aramaic, and Greek; Second Temple Judaism and post-biblical Jewish texts (including Mishna, Qumran, and the Targums) in Aramaic and Hebrew, and a host of other Bibles and classical sources. Many or most of these are grammatically tagged.

You can also add on modules like the classic Brown Driver Briggs Hebrew-Aramaic lexicon (the famous 'BDB') and the fabulous Koehler-Baumgartner dictionary. I have not even kept up with OakTree Software's recent forays into Bible Atlases and Photo Guides, but I've seen enough to know that I'll be impressed when I do.

As a value added, the good folks at OakTree put on workshops for users, where oohs and ahs are to be heard emanating from users like me who suddenly realize that Accordance can even do *that*!

Perhaps most remarkably of all, OakTree staff actually answer phone calls and emails, promptly, helpfully, and without making you feel like a techno-maggot."

"I have been involved in serious Bible study for nearly 30 years now and have used many different Bible Study software programs. On switching to a Mac in 2001 I was given a copy of Accordance as a gift after speaking at a conference. What a gift! I was amazed at what Accordance was able to do. My friends and I used to discuss what the ultimate Bible software program would do. To my amazement Accordance provided everything we ever longed for and much more that we hadn't thought of.

From that point on Accordance has been my constant companion. I travel extensively and am amazed that as I travel I can carry with me a wealth of translations, commentaries, dictionaries, maps, my own help notes and even an electronic version of my Bible highlights. What would have required many suitcases to carry in the pre computer days is now instantly available to me just by opening my laptop. The personal support, constant upgrades and improvements, and professional service all make Accordance the one Bible software tool no serious Bible scholar should be without. Thank you Oaktree Software."

A good friend of mine turned me on to Accordance a few years ago, and I’ve been hooked ever since. The icon is a mainstay on my desktop, as I constantly use the program for research and quick reference. I also incorporate it when teaching to enhance lectures and seminar discussion. Accordance has also saved me hours of library time by providing valuable information that is only a few clicks away.

"I've used and reviewed all the major players in the Bible software field, and all of them can do amazing things. At the end of the day, however, the program I rely on most for study and teaching is Accordance. With its nimble navigation functions, speedy search capabilities, and impressive collection of tightly integrated resources, Accordance 8 is more than a Bible study resource – it’s like a genie on a hard drive, with no limit on wishes."

"As a student of Scripture for twenty-five years I've continually been searching for the perfect Bible Software. I have never been more pleased than I am with Accordance. I use it not only for preparing talks, but I use it during my live national talk radio show. In a fast paced morning show I need information quickly and efficiently, and Accordance does just that. I also host a live national TV show and I can't tell you the number of times that Accordance has helped me just minutes before going on the air. Thank you for a simple, powerful and intuitive software package."

"Accordance is a great Bible program - one I always talk about. I've taught several college courses on hermeneutics and have always plugged Accordance as the "must have" Bible program. Its commitment to the accuracy of original texts, the commentaries and other resources are plentiful. Besides, this program is the best at being "user-friendly."

In my personal Bible study, aside from wanting to touch a paper page occasionally, Accordance is the program I use for sermon and classroom teaching preparation. I cannot say enough good things about this program."

My favorite feature of Accordance is the powerful search engine itself that allows me to do complex linguistic searches in seconds. For example, I can very quickly check how a given word is used in countless Aramaic and Syriac contexts from the iron age to the Byzantine period. But I can also do complex grammatical searches on various morpho-syntactical features in all of the grammatically tagged modules in Accordance. Since my field is Comparative Semitics, it is useful for me to have as many Semitic texts in Accordance as possible, and that number is growing all the time.

But the Accordance texts also allow me to do my weekly reading of the Torah and Haftarah portions and help in teaching the Semitic languages. With regard to weekly Bible reading, it is a Mitzvah in Judaism to read through the Torah each week twice in Hebrew and once in translation (and for the Haftarah once in Hebrew and once in translation). So each year I rotate among nine languages (Jewish Literary Aramaic, Jewish Palestinian Aramaic, Samaritan Palestinian Aramaic, Christian Palestinian Aramaic, Late Jewish Literary Aramaic, Syriac, Arabic, and Classical Ethiopic) as to which language I will read alongside the Hebrew. So I love being able to open the parallel texts alongside the Hebrew and read them together. I like to gloss the words I had to look up in the margins of my hard or computer copy, and Accordance helps me do that quickly for most of those languages.

For teaching, I am able to show students actual examples of various grammatical constructions, print out frequency charts for vocabulary learning, prepare quizzes, etc. with Accordance. While class preparation still takes time, Accordance has greatly reduced the amount of time required. Using the projector to demonstrate Accordance in the class also allows me to teach the students professional linguistic research methods.

"I wanted to personally thank you for Accordance. I cannot even begin to tell you how much this program has meant to me. For the greater part of my life I have studied the Bible but it is in the past year or so, since I purchased Accordance that my studies have taken on a new depth. Accordance is an astonishing piece of software, and rivals any application of any kind that I have ever used. I bought my Mac only to use Accordance (I use Windows Vista for most of my others tasks) and have not looked back. Particularly in the area of original languages I have found Accordance to be special. I suppose you hear this all the time, but I don't suppose hearing it again will do any harm."

"Accordance for the Macintosh is by far the best computer Bible program available today. In addition to searching many Bibles in various languages and tools like Hebrew and Greek dictionaries one can also search individual modules separately (e.g., Qumran Sectarian MSS, Pseudepigrapha, Mishnah in Hebrew or English, or Apostolic Fathers in Greek, Latin, or English), a boon for the serious student and scholar alike. For its user friendliness, for the speed of even complex context searches (most take only a second or two), and for the enormous amount of material that is available (literally) at one’s fingertips, Accordance will simply astound even a jaded computer buff. A splendid program that keeps getting better and better and easier to use."

"I have used Accordance software for ten years and will keep on using it as long as I pursue biblical studies. I have used other Bible software and none of it compares to the power, efficiency, and ease of Accordance. I recommend it enthusiastically."

Accordance is an indispensable teaching and learning tool. I started using it as a graduate student and was hooked on the free demo version. I was using another product but was sold on the interface: simple, elegant and efficient. Accordance was also cost effective, allowing me to buy only what I needed and could afford. My students love Accordance and find that they are able to use it from the moment they learn their Hebrew and Greek letters. I particularly appreciate the ability to customize my collection of Accordance modules to fit my research and teaching needs. Their library holds a vast array standard scholarly reference tools in an easy to use  platform. Accordance also provides some of the best technical and customer support I have ever received, and excellent user-friendly instructional materials. My faculty does require Accordance for Macintosh users. I highly recommend Accordance for graduate and seminary students, pastors and professors.

"Mac people think differently than PC people. The Mac user requires a software work environment that is intensely intuitive. And the Accordance software is the most intuitive that I know. As smooth as silk, one can set up a passage or a word search, and move effortlessly through the myriad of illuminating tools that Accordance proffers. I have never used an owner's manual, written instructions, or Accordance tutorial ... but I always can find what I want! Amazing!"

I really appreciate the Accordance programme. I use it every week in sermon preparation. It is basically open on my desk top all the time. Being solidly based on the Greek and Hebrew Texts encourages careful exegesis. I’m only sorry that it was not available when I was at college and the years following for it makes working in the Hebrew text manageable in a busy parish ministry. Having the text of Scripture keyed into first class tools like the Bible dictionary enables me to travel to conferences with my library in my laptop.

I use Accordance daily for searching the Greek NT, the Hebrew OT, and the Septuagint, and use it often also for Josephus and Philo and other sources that augment my understanding of the context of Scripture. It’s hard for me to imagine now how I was writing commentaries before I had access to this wealth of resources, which it puts at my fingertips quickly and efficiently.

In the 1980’s I began teaching in Seminary and realized that I needed to invest in a computer to further my work. However, the computers available at that time did not particularly interest me. Then Apple unveiled their Super Bowl 1984 Macintosh ad. I was hooked. This was a real computer! I purchased a 128K Mac – all the memory that I would ever need!

Before too long, I learned how to get the Hebrew Scriptures on disc, paste text into handouts for class and create overhead transparencies. I tried all kinds of Bible software, on various platforms, and finally found “acCordance” for the Mac with The GRAMCORD Institute in 1994. Computer Bible study with Accordance became an essential supplement to my study and teaching. Through the years this progressed to better handouts and computer projected presentations. Beginning in 2004, with the maturing of Accordance, Hebrew/Greek/English computer Bible study moved more and more to the center of my study and teaching. Today Accordance is both central and essential.

I am delighted with the ever-expanding capabilities that the people at OakTree Software have brought to Accordance and highly recommend it to my students, colleagues, and all students of the Bible. The staff has always been extremely helpful in assisting me with purchases, especially given my nontraditional route into the modules. I appreciate the fact that students can begin their journey with a more modest investment and then add modules as they have resources. The many training tools further enhance Accordance’s already user friendly interface – David Lang’s Training DVDs, Tim Jenney’s podcasts, written documentation, revised Help screens, User Forums, and Training Seminars (I recently attended my first). And now it is so easy to pop pictures and charts into projected presentations as well as to project Accordance itself for classes and churches.

Today, my laptop (or iPhone or iPad) with Accordance goes with me wherever I go, both for my own reading and study and for teaching. My electronic library is with me whether I am teaching at my own Seminary in the US or teaching overseas. As I have traveled in other ministries, it has been great to have so much so conveniently at my fingertips wherever I am. I look forward to many more exciting developments and capabilities in the years to come! To paraphrase someone else in another context, I started out looking for a Piper Cub and what I have found in Accordance is a 747!

"Accordance is, simply put, the very best piece of software in its class. It makes my research and writing significantly easier. If you don't have a Macintosh or iPad, Accordance makes the purchase worthwhile.

When it comes to research, it is hard to know where to begin the praise. The search can be simple and it can be powerful, straightforward and never really complex. I have yet to find anything for which I cannot search. In doing statistical work for Basics of Biblical Greek, not only for words but for longer phrases and grammatical constructions, Accordance has always been able to give me the right numbers. The databases are accurate and trustworthy, not giving me false positives.

Cosmetically, I can arrange the windows any way I want. I can keep texts in sync. With zones I can now keep my main text before me and do my searching in other synced windows. I can put commentaries and study notes within easy access without crowding out the biblical texts. It is like Accordance was thinking of me when they built such a flexible interface.

In terms of research, I continue to be amazed at the depth of their reference books. They have almost every reference book and commentary series I use. And they are aggressive at continuing to get more. If you buy into their system, you wouldn't be disappointed down the road. This is especially true if you are in Old Testament studies; the depth of their esoteric references is mind boggling.

As I have worked on the translation committees for both the ESV and the NIV, I have found Accordance essential. They have all the translations, many of the original texts (including papyri), all presented in such a way that it makes translation much easier. If you like either of those translations, you can thank Accordance.

And finally, technical support is excellent. As always, please read the manuals, but if you still have questions you can get help. The new Web site is especially helpful, giving you quick access to your purchases with nearly automatic downloads.

Thanks Accordance."

"After playing with Accordance for a few months, the verdict is in. It’s sweet. If you need a good -- no -- great Bible study aid, ain’t nothing going to touch this. It’s that good. While it has its share of deficiencies, they are minor and heavily overshadowed by the brilliance of the rest of the program. As we state in the review, it may be reason enough to turn PC users into switchers for sure!

Take a look at the review and then take a look at OakTree’s site. You’ll be amazed at the power you’ve been missing in God’s Word!"

"Throughout the writing of my chapters for the new atlas, The Sacred Bridge, Carta's Altas of the Biblical World, I made constant use of the Accordance Program. The need to cite many passages from the Hebrew Bible, the Greek Septuagint and other sources (including the Targums) was made easy by using Accordance (then version 6). The use of several columns in a Search Window let me see the Hebrew, the Greek and some times certain English translations all in a glance. Countless hours were saved by the quick search capacity of Accordance.

Some of the reference tools were also found indispensable. The outlines and bibliographies of articles in the Anchor Bible Dictionary were a great help and saved me the need to spend hours in libraries.

My partner in this project, R. Steven Notley, also made similar and constant use of Accordance for his chapters in New Testament and Second Temple historical geography.

Now, with Version 7, I look forward to many happy hours of productive writing during which I will have the powerful resources of Accordance at my fingertips.

It is also a pleasant opportunity to express my appreciation for all the expert staff members. They have always supported me with the highest of professional support accompanied with a cordial and cheerful attitude. The are genuine servants of our academic community."

"After years of working with [other software], Accordance quickly advanced to be my workhorse. The simple and intuitive interface kept the learning curve short. Working with original language texts is so easy that even beginners will find Accordance helpful. The layout of the construct searches is intuitive and automated. However, this simplicity is a little devious. The possibilities of creating complex searches are so far reaching that they can hardly be exhausted. Especially attractive are the possibilities of creating searches for whole groups of texts. Finally, Accordance is very speedy.

Nevertheless, the decision for Accordance entails a substantial financial investment. For this one gets the best bible program on the market today."

"I like to have the very best in conjunction with the very best. For computers this is Macintosh and for programs this is Accordance. Accordance is the most user-friendly program that has the most texts and tools I am interested in. Of course you have to learn the program, but once you know the major principles everything else becomes very easy. I like Accordance for my own work and for my students. The major area of my interest is that of the philological and textual study of the Hebrew and Greek Bible. For my own work in this area I now use Accordance more than printed books. With a wide screen I can see several sources at the same time. I print out some results, although I always have one of my laptops with me in my courses. I am amazed at the quality of Accordance and at the beautiful results I get for very sophisticated search questions. The excellent dictionaries of Accordance help me to get to all the required words, phrases, and combinations. The graphs, analyses, and concordances are absolutely fabulous.

I enjoy exploring the various aspects of the Hebrew text of the Bible, alone, and in conjunction with its various ancient translations, and now also with the Samaritan Pentateuch, and soon with the Biblical Qumran scrolls. All these can be shown in parallel windows, and in the case of the Hebrew and Greek Bible, with every version of Accordance the comparison is more sophisticated and user-friendly. I also enjoy the wealth of ancient sources around the Bible. Three years ago, I founded at the Hebrew University a computer course within the Dept of Bible that is based on Accordance. That program is now installed in the library and at the server of the Computer Instruction unit on Mt Scopus, so that students can actively use the program.

I am happy with Accordance, and I am proud of it."

I purchased the super bundle just before duty travel a couple months ago and, several times now, I've really wanted to send an e-mail just to say thanks for such a great product.

The amount of material that you've provided in the bundle is staggering but Accordance makes it practically effortless to access information right at the moment that it is relevant or interesting to me. In fact, Accordance has made Bible study so much more accessible and interesting that, even after two months, I'm still excited about the daily, morning studies that I began on the day that I purchased it.

During the last few of days, I had to put my Mac aside so I was back to my old, limited set of printed texts. Not surprisingly, I had completely forgotten how frustrating it is to have so many unanswered questions or to be stuck with my own speculation regarding context, the meaning of words/phrases or even just a location on a map. I had also forgotten how much time I consumed this way with flipping pages, jostling volumes, countless bookmarks and scribbling/filing my unreadable notes. ;)

I'm embarrassed to admit it, but my devotion to reading and studying the Bible had dwindled almost to nothing during these last several years. However, since I bought Accordance two months ago, it has re-awakened the first-love interest and excitement about the Bible that I felt so long ago, when it was all so new to me.

Thank you for that.

On a side note, my wife was really skeptical about the value of the purchase, based on her observances of my Scriptural neglect these last several years, but she's pretty impressed with the results.

I am currently doing an extensive essay needing to use Accordance three and four times each sentence with the Greek language.  It is ardous but Accordance is making it a dream.  I am so excited with your product and want to thank you immensely for it.  I couldn't be the student I am without it.  Teachers and students are always asking me in class to look it up and find out what it says, I am just amazed at how often it is used for the furtherment of the Gospel.

Thank you so very, very much from a very grateful student, (and yes, I do try and get them to buy it themselves).

I am officially hooked. I have flirted with sermon prep/Bible study software through the years, but the flirtation has always been brief. With Accordance, the experience has gone from flirting to a long-term commitment. After purchasing a few additional modules, I now have everything need to do all my sermon preparation on my computer. It truly takes this experience to a new level. Thanks for a great product. I am very grateful.

O... BTW... I've got to tell you that I used xxxx for year on my PC... I was hesitant when I got my Mac last year to switch to Accordance, but after I did... just like with my Mac... I was... "WOW!"  I know that doesn't sound very scholarly... but all I can say every time I use Accordance is "WOW!  I can't believe I waited so long to switch to this program!"

As a lay person interested in serious Bible study, Accordance is a dream come true. While its true power is unlocked for those who study in original languages, I can't imagine the hours of work I would need to do to perform simple tasks, like finding out how many times the word "prayer" is used in a range of books. It takes maybe 5 seconds for me to tell Accordance what I want it to find, and in literally 1 second it returns the results for me to read through. Better still, I can instantly compare the results across multiple translations. I do this kind of search regularly, and the search feature alone is worth the price of admission -- and it's a small part of what Accordance can do. I can confidently say that Accordance is as indispensable for the layperson as it is for clergy.

Your new Atlas is fantastic! I have been using the old one for several years in my PowerPoint presentations and, just recently, was augementing the Atlas geography with Google Earth pictures (which are fairly "muddy" much of the time). But the new detail on your Atlas is so much better as a teaching tool than Google Earth that I have already started converting some of them back. Congratulations on a great product and thanks to you and your staff.

I have no problem with my words being used for publication. I am completely in love with the Accordance Bible software, which is why I would like to upgrade it instead of switching..... I have used (other software) on Windows for years and recently switched to Accordance. One of the first things I noticed was the simplicity of the program. It is incredibly easy to use. I watched the tutorial and have not had a problem since when it comes to accessing the features of Accordance. It is somewhat of a paradox, however, in that the ease of the program is combined with the in-depth analysis of the text. I have little need for the superfluous books and texts that come with other programs. I simply want to study the original texts of Scripture.

I love Accordance because it is easy to use and, compared to other Bible software, offers me in-depth analysis of the text without having to shuffle through extra things which add little to the meaning of the grammar and syntax in the original languages. From finding a single word to finding complex syntactical and grammatical strings within the text, Accordance is hands down the premiere Bible software available for any operating system.

In comparisons with other Bible software, I enjoy the fact that I 'get right to the point' with Accordance: analysis of the original text. The way that the diagram feature separates the words using colors for different parts of speech is simply brilliant. When features like this are paired with the best atlas and maps feature in any Bible program along with the best commentaries available today, it makes for a great program that I would not want to be without.

That pretty much sums up my feelings about Accordance. You have set the bar towards which every other Bible program should aim.

This really is phenomenal work! It is beyond Macworld mice and design awards. Truly phenomenal!

Shalom, I just wanted to let you know that I think The Babylonian Talmud module excellent. Your software really helps me in my Torah studies.

Let me tell you ... This software completely blew me away in terms of how much easier it is to use compared to xxxx. I took my time as I went through the brief tutorial included in the help files, and after a couple hours, I was overwhelmed - not by the amount of information to learn - but the incredible simplicity and elegance that is built into the Accordance interface.

I can't wait to go home and use Accordance to enhance my Bible reading and personal study, and I am looking forward to adding more 'modules' (Bibles, Commentaries, Language helps) as time and finances allow.

I just wanted to let you know how much I appreciate your software.

I have been a customer of yours for a few years now and I am consistently impressed with your scholarship, your innovation and your work ethic. I can safely say that I use your software everyday, and that its simplicity and ease is a real joy. The speed that I can jump from source to source and commentary to commentary is marvelous. I travel extensively and when I'm away from my library at home just the assurance that my computer contains all the writings of the Fathers, the Mishnah, Schaff, Philo and others gives me a tremendous sense of comfort.
