This form of book-card may be ruled to take the borrowers’ numbers and dates of issues, and is one of the main accessories of the card system described in Sections 380, 381. =218.= With indicators it is necessary to write the accession numbers on to the indicator books or tabs according to the style of indicator used. In forms such as the Elliot, the number is already fixed on the indicator frame and requires no additional book tab or block. Other processes connected with book numbering for shelving purposes are considered in Chapter XXV. =219.= The next process is the LABELLING of the books. Reference library books are usually labelled on the inside of their front boards with the library book-plate, which may be an artistic device, or a simple label bearing the town’s arms and a few of the chief rules of the department (Fig. 64). Some libraries add a label ruled in columns to show dates of issue, but this does not seem particularly useful. Lending library books are labelled with a label pasted down on the inside front board bearing the chief rules for borrowers, and with a date label secured to the front fly-leaf by means of a narrow line of paste on the inner edge.
