I couldn't find any previous requests, but I would greatly value the addition of The Encyclopedia of Hebrew Language and Linguistics, published by Brill.
From the publisher:
"In a four volume set, complete with index, the Encyclopedia of Hebrew Language and Linguistics offers a systematic and comprehensive treatment of all aspects of the history and study of the Hebrew language from its earliest attested form to the present day. The encyclopedia contains overview articles that provide a readable synopsis of current knowledge of the major periods and varieties of the Hebrew language as well as thematically-organized entries which provide further information on individual topics, such as the Hebrew of various sources (texts, manuscripts, inscriptions, reading traditions), major grammatical features (phonology, morphology, and syntax), lexicon, script and paleography, theoretical linguistic approaches, and so forth. With over 950 entries and approximately 400 contributing scholars, the Encyclopedia of Hebrew Language and Linguistics is the authoritative reference work for students and researchers in the fields of Hebrew linguistics, general linguistics, Biblical studies, Hebrew and Jewish literature, and related fields."
