[1] The Guide was written in the first decade of the twentieth century by Alice Bertha Kroeger, head of the Library School at Drexel University in Philadelphia, Pennsylvania.
After taking the volume through three decades and four new editions, Mudge retired and passed the responsibility on to her successor at Columbia University, Constance Mabel Winchell.
Winchell reorganized the book, classifying the indexes into different disciplines similar to the academic departments of a university.
The indexes were greatly expanded under Winchell; when the eighth edition was published in 1967 it was quite a tome, including entries on some 7500 individual publications.
Having worked as Winchell's assistant for several years Sheehy adopted her style, process of selection and organization as his own.
No longer the vision of a lone individual, the Guide became an increasingly cooperative project as reference literature grew and as contributors were drawn from libraries around the country.
The online Guide's last general editor was Denise Beaubien Bennett, engineering librarian at the University of Florida's Marston Science Library.
