Excerpt from Abbreviations and Technical Terms Used in Book Catalogs and in Bibliographies: Book Catalogs and in Bibliographies In the present revision a number of errors which crept into the final proofs, in spite of repeated readings by several com petent collaborators thoroughly familiar with the languages represented, have been corrected. Several librarians and book sellers have given further aid in the revision. Among them special mention is due to Mr. Alfred Hafner and the staff of G. E. Stechert Co., and to Mr. Moth and Miss Plummer of the New York Public Library. Although an honest attempt at accuracy has been made it is not probable that all old errors have been detected or all new ones avoided. It is hoped that such as do remain may not prove misleading, however much they may vex the soul of the fastidious bibliographer.. Several considerations, among them the expense of biblio graphic publications, have prevented any considerable changes in content or scope. This is still a tentative preliminary list based, both as to inclusion and exclusion, on observation of the difficulties most frequently met in the use of ordinary trade bibliographies. It can, consequently, claim neither well-balanced proportion, entire consistency nor completeness. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
