Excerpt from Guide to the Study and Use of Reference Books The third edition of the Guide is based, in the main, upon the second edition, 1908, and the two supplements for 1909-10 and 1911-13, but the many changes in reference books and developments in reference work and teaching since 1908 have necessitated many changes from the earlier edition. In the third edition the general plan and ar rangement of the second edition have been followed and Miss Kroeger's Introduction, familiar to so many classes of library students, has been kept intact except that one section, How to study reference books, has been made slightly more detailed. The lists of reference books, however, have been changed very materially and the annotations have been rewritten and much extended, so that this latter feature of the Guide is prae tically new throughout, only a few annotations having been carried over from the second edition, although somewhat more have been retained from the two Supplements. Aside from the new annotation, the revision of the lists of reference books has consisted principally of (1) excision of older titles and editions now superseded by more recent material, (2) addition of new titles including not only the recent books listed in the two Supplements and later titles through 1916, but also a very considerable number of earlier titles. Principally foreign or more special works not hitherto included in the Guide, and (3) the addition of some entirely new lists, such as those on Constitutions, International law, Romances, Historical source books, English public documents, etc. Among the older lists Which have been greatly augmented are those on Periodical indexes, both General and Special, Foreign dictionaries, Statistics, Author dictionaries, Concordances, Special gazetteers, Place names. In general, information included goes through 1916, and does not cover changes, additions, etc., for 1917.
