For the various kinds of bibliographies see Mudge’s “New guide to reference books” (or Kroeger’s “Guide to study and use of reference books”), Stewart _and_ Clarke’s “Book selection,” “List of bibliographical works in the Reading Room of the British Museum,” Brown’s “Manual of practical bibliography,” and Gross’s “List of books and articles chiefly bibliographical, designed to serve as an introduction to the bibliography and methods of English literary history.” The Universal bibliographies by Brunet, British Museum, Burger, Ebert, Graesse, Hain, Maittaire, Panzer, Peddie, Pellechet, Proctor, Watt, etc. For a comprehensive list of National bibliographies of 49 countries _see_ Peddie’s “National bibliographies: a descriptive catalogue of the works which register the books published in each country.” _London, Grafton, 1912._ _Add the_ United States Catalog: books in print to January, 1912; edited by M. E. Potter and others, and the Cumulative book index. _White Plains, New York, Wilson, 1898-1922. Vols. 1-24._ (These two are not included in Peddie’s work;) also the New York State Library. Selected National bibliographies. _3rd edition. Albany. University of the State of New York, 1915. (Library School Bulletin, No. 38). 10c._ The following trade bibliographies should be noted:--American catalogue of books, Book auction records, Publishers’ trade list annual, United States Catalogue, Livingstone (America). Arber, Book prices current, British Science Guild, English catalogue of books, Growoll, Whitaker, etc. (English); Catalogue Annuel. Lorenz, etc. (France); Heinrich, Heinsius, Kayser, etc. (Germany); For general bibliographies the most important are Sonnenschein’s “Best books,” Nelson’s “Standard books,” Gray’s “Books that count,” Robertson’s “Courses of study”; and for American books, the A.L.A. book list, 1905 to date. A mere acquaintance with the titles of the bibliographies etc., will be of little service. Students must know the general scope, method of arrangement, standpoint, and comparative usefulness of each. It must be remembered also that many of our best bibliographies and guides appear in the Latin, French, and German languages. READING LIST.
