Exceptions do occur, but very seldom, and then only in the case of very early writers, when the full name is best given, _e.g._, Jean de la Bierre. When prefixes are embodied as part of a surname, it must be catalogued as one name, _e.g._, Delarne-Mardrus, Lucie. In cataloguing Latin books the following codes must be studied: Quinn--Manual of Library Cataloguing, _pp. 128-130_; Cutter--Rules for a Dictionary Catalogue, Section _30_, and A.L.A. & L.A. Cataloguing Rules. It is now the general practice to enter Latin authors under the English name, as adopted in our standard biographical dictionaries, such as Smith’s “Dictionary of Greek and Roman Biography,” and Harper’s “Dictionary of classical literature and antiquities.” In a great number of cases, however, these dictionaries enter under the Latin or vernacular form and the beginner in cataloguing Latin books is soon in difficulties, and still greater confusion results where an author has three names, as Titus Lucretius Carus, or Caius Suetonius Tranquillus, he does not know which is the best name. The nominative case is the best for the heading in practically every case. In order to become familiar with the names of Latin authors the beginner should know the case endings of the various declensions, especially the nominative and genitive plural, also the indexes to the following books may be profitably perused: Crutwell’s “A history of Roman literature,” also Appendix at _pp. 483-489_; Dimsdale’s “A history of Latin literature”; Duff’s “A literary history of Rome”; Wilkins’s “Roman literature.” A careful observation of the various names should enable the cataloguer to recognise them when a Latin book comes along, for instance in P. Ovidi Nasonis Tristium. Libri V. Recensuit. Catulli, Veronensis liber: iterum recognovit. P. Terenti, Comoediæ. T. Macci Plavti Rudens. The student should be able to select the names Ovidi, Catulli, Terenti and Plavti and from these we get the Anglicised names Ovid, Catullus, Terence and Plautus. THE PRINTED CATALOGUE. The printed catalogue is rapidly disappearing due chiefly to the high cost of printing and the almost universal adoption of the open-access system. A card or sheaf catalogue, supplemented by bulletins or occasional lists, is in use in most libraries, but the following still find it advisable to issue Class Lists: Bolton, Brighton, Burnley, Finsbury and Glasgow. In each case the Dewey Decimal Scheme is the plan of arrangement. The following libraries issue printed bulletins or reader’s guides:--Coventry, Croydon, Ipswich, Norwich, Nottingham and Warrington. SPECIFICATION FOR PRINTING A CATALOGUE. The best way to have a catalogue printed is first of all have a specimen page “set up,” with entries that will bring in all the types to be employed. This, together with a copy of the specification may be sent to six different firms inviting them to tender for so much per page.
