CO-OPERATIVE CATALOGUING. CENTRAL CATALOGUING BUREAU; UNION CATALOGUES. CATALOGUING FOR SPECIAL PURPOSES:--CHILDREN’S CATALOGUES, BULLETINS, LISTS, ETC. Study definition of each style of catalogue, author, subject, dictionary, classified, alphabetical-classed, etc. The dictionary and classified forms are mostly in use, and opinion is divided as to which is the more suitable style for a public library, each claiming merits not possessed by the other. In order to decide which style most adequately serves the needs of the particular public using the library, consider what questions are likely to be asked of a catalogue which it may be reasonably expected to answer, and see to what extent these are met by the respective styles of catalogues. The policy of establishing a Central Cataloguing Bureau in England is under constant reference. Study the advantages claimed for, and difficulties to be surmounted by, such a department. To what extent does the Library of Congress card scheme satisfy requirements in this direction? Many suggestions have been made with a view to co-operation in cataloguing. Consider what it is claimed possible to accomplish in this direction, and note what has been attempted towards this end. The Manchester and Glasgow union catalogues are notable examples of co-operation in order to give fullest information on a particular subject available in the locality. Carefully consider the utility of these attempts at co-operation, and the possibilities underlying the various suggestions which have been made. Note the extent to which the usual cataloguing practice is modified when compiling children’s catalogues, lists, bulletins, etc. READING LIST. VARIETIES OF CATALOGUES:--
