 Use of the Guide became less and less frequent as research had turned more towards electronic databases such as EBSCOhost and JSTOR.The project to develop a 12th edition of the Guide as an online database was announced in 2000 under the editorship of Robert H. Kieft, then librarian at Haverford College (now college librarian at Occidental College).This online edition was published in 2009 and continually undated.
