It includes usually only the class- and author-number, author's name, brief title, and accession number.

This last enables one to refer at once from the brief entry of a certain book in the shelf-list to the full information in the accession book.

There are advantages in adding to the shelf-list record the publisher and price.

As soon as a book has received its class- and author-numbers, which together are sometimes called the "call-number," as being the mark to be used by the public in calling for a book, these numbers, or combinations of numbers and letters, should be written in the accession book in a column left for the purpose, on the line given up to the description of the book in hand.

This enables one to refer at once from the accession entry of a given book to the shelf-list entry of the same book.
