_6._ Describe briefly the various kinds of catalogues. State which you prefer in an open-access library, giving reasons for your choice. _Lesson 8._ FORMS OF CATALOGUES:--CARD, SHEAF, PRINTED, PLACARD, ETC. METHODS OF DISPLAY. The librarian’s choice of catalogue does not end with the decision on a dictionary or a classified variety. The form of the catalogue has also to be considered. Of the three main forms--card, sheaf, and printed, the number of each kind in use at the present time testifies to the varying opinions held as to their suitability. Study the considerations affecting the choice of any one of these, and the advantages claimed for each. In order to ensure the fullest use being made of the catalogues by the public, no effort should be spared in making them most conveniently accessible. Although the devices invented to achieve this end are so numerous, many of them are mere variations of the same principle, and although opportunity must be taken to see as many different kinds as possible, an examination of a device illustrating each principle will enable the student to grasp the underlying idea of all.

Illustrate by a rough sketch. _4._ Describe the principal methods of displaying catalogues. Which method do you prefer, and why? _Lesson 9._ PREPARATION OF THE PRINTED CATALOGUE. Note the various decisions required in planning a catalogue--edition, size, type, paper, binding. Draw up a sample specification. Study the practice in obtaining tenders, and considerations necessary in deciding upon the most suitable. Careful preparation and marking of the copy will save troublesome corrections at a later stage. It must be clearly marked to show the printer the various changes of type. Learn the correction marks used in checking proof. Attention must be given to the necessary captions, etc., when checking page proof. Considerations regarding type will be simplified by a knowledge of the Point System of type measurement (see paragraph on page _24_). READING LIST. Philip---Production of the printed catalogue.
