Digital Scholarship 2009 includes four bibliographies: the Scholarly Electronic Publishing Bibliography: 2009 Annual Edition, the Institutional Repository Bibliography, the Electronic Theses and Dissertations Bibliography, and the Google Book Search Bibliography. The longest bibliography, the Scholarly Electronic Publishing Bibliography: 2009 Annual Edition, presents selected English-language articles, books, and other printed and electronic sources that are useful in understanding scholarly electronic publishing efforts on the Internet. Most sources have been published between 1990 and 2009; however, a limited number of key sources published prior to 1990 are also included. Peter Jacso said in ONLINE (vol. 27, no. 3 2003, pp. 73-76): "SEP [Scholarly Electronic Publishing Bibliography] is compiled with utter professionalism. It reminds me of the work of the best artisans who know not only every item that leaves their workshops, but each component used to create them--providing the ideal quality control. . . . The selection of items is impeccable. I have yet to find journal articles irrelevant to the scope of the bibliography. SEP could be used as a benchmark in evaluating abstracting/indexing databases that proudly claim to have coverage of electronic publishing, but do not come close to SEP."
