It will be clear that, in view of the impossibility of printing the Anglo-American Code in this chapter, it will be futile to give an alternative Code in a manual which deals with the general activities of the profession. A brief Code did appear in the last edition, which was practical and simple, and reference may be made to that, but it is strongly to be suggested that all future catalogues should be accommodated to the A.-A. Code in order that uniform methods of entry may be perfected, catalogues may become more generally understandable, and a formidable obstacle to co-operative cataloguing be removed. =264. Bulletins.=--Since about 1894 a number of libraries have issued periodical magazines, or bulletins, in which are printed lists of new books, reading lists on special subjects, notes on the work of the libraries, and other matter likely to be of use and interest to library readers. The first use of such a magazine is to supply readers with a regular supplementary catalogue of all book additions; a second purpose is to publish notifications of new rules or alterations in the working of the library; and a third may be to issue information about the work accomplished by the library. The greatest amount of space, therefore, should be allotted to the description of new books, and annotations should be supplied liberally to the entries which require them. The magazine has the advantage over ordinary supplementary catalogues in that it is issued regularly and frequently; and it has a valuable purpose in supplying printed entries by means of which the card or sheaf catalogue can be kept up-to-date effectively. Copies of the magazine can be printed on thin paper (preferably bank paper) on one side only, and the entries can be cut out and mounted on cards or slips and inserted in the standard catalogue of the library, whatever form it may take. Emphasis may be laid upon the special catalogues or reading lists which can conveniently be published by this means. A special catalogue is usually a classified list of entries on the subject chosen in ordinary catalogue form, of which several good examples appear in the Norwich _Readers’ Guide_. A reading list has a directive purpose; it is in a much freer form as a rule, selects the best books on the subject, and indicates the order in which they may be read most profitably, with qualitative and elucidatory notes. Examples of such lists appear in several American library bulletins, and examples readily accessible are those in the Croydon _Reader’s Index_, a sample from one of which is subjoined: =DARWIN AND THE EVOLUTION THEORY= =PART 1. INTRODUCTORY COURSE.= For those who are unable to read very widely in the theory the following are suggested, in the order given, as sufficient for giving an accurate and fairly complete view of the question. =Saleeby’s= “Organic Evolution,” a simple but interesting intro. to the subject =C=[11] 575
