When a catalogue of a particular class of literature is separately published it is called a _Class-List_. A catalogue of novels, or of poetry, or of music would be so termed.

By the term _Dictionary Catalogue_ we understand a combination of the first three, viz., Author, Title, and Subject catalogues in a single alphabet.

The last two forms when thrown together, not in alphabetical but in logical arrangement, make the _Classified Catalogue_.

Library Cataloguing — Part 19

The same two if arranged alphabetically and not logically form the _Alphabetico-Classed Catalogue_. With this last form the author-catalogue could be combined without any disturbance of its arrangement. It can only be added to the classified as an index or appendix.

To study systematically the various codes of cataloguing rules is of great value to the beginner in the work of cataloguing a library, though the apparent variations and contradictions in the codes are at first somewhat confusing. Their practical application to work in hand serves better to prove the usefulness and necessity of adopting some code or a modification of it before much progress is made. Once a choice is made, it is better to adhere to it uniformly throughout.

The purpose of the catalogue has a bearing upon the nature of the stationery required. A catalogue cannot be written into a book like an inventory; each item--even books by the same author or upon the same subject--must be upon a separate paper slip or card cut uniformly to any size fixed upon. Paper slips serve quite well for manuscript, or "copy" as it is termed, for the printer, but tough cards of good quality are needed for a catalogue on cards to be handled by many persons. It is a good plan in any case first to prepare the catalogue upon slips or cards for office use; then, when checked and revised, to copy from these for public use, either upon the good quality cards as suggested, or into the book-form of catalogues with separate leaves, known as "sheaf-catalogues." This last-named form is preferable for public use, and takes up less room. Any size of slips or cards may be adopted provided they are exactly cut to a fixed size, 5 inches by 3 inches being convenient; or the size usually provided with the index filing outfits, now so generally in commercial use, which were first used in the cataloguing of libraries, and then applied to other purposes. If the slips or cards are for handwriting, they should be ruled "feint" across, and whether so written or typed, are better with red lines marking margins of about half an inch at each side. If written by hand, the writing should be round, clear, of fair size, and above all, free from flourishes, whether written for public use or for the printer.
