Hi phil, The wording refers to emerging concerns over the use of secondary sources:
November 4, 2016
In the summer of 2016 Zondervan Academic became aware of emerging concerns that one of its authors, Dr. Peter T. O’Brien, may not have followed commonly accepted standards for the use and documentation of secondary resources in Bible commentaries he had written. Consequently, we began a careful review of Dr. O’Brien’s commentary on Colossians and Philemon, volume 44 in the Word Biblical Commentary (WBC).
It is with sadness and regret that we have concluded this volume does not follow commonly accepted standards for the use and documentation of secondary resources. Dr. O’Brien is revered by his colleagues in the academy and by his former students. His commentaries, including volume 44 in the WBC, have been used with great benefit by the thousands who have purchased them. While we have no reason to believe that Dr. O’Brien intentionally misused secondary resources, our commitment to high publishing standards leaves us no choice but to put volume 44 of the WBC out of print in both its print and digital formats and to destroy the remaining inventory.
