It is the key to the records in shelf-list and accession book.

In a small library the public may very properly use it.

As soon as possible, if your library is to be quite large and much used, prepare for public use a duplicate of it, omitting all those entries in the original which are of use only to the librarian.
The average reader more often remembers the titles of books than their authors.

Add, therefore, to the author-list, in your public catalog--not in your private or official catalog, for which author-entries alone are sufficient--a title-list; a set of cards like the author cards, except that on each one the book's title is entered first instead of its author.

Arrange author and title-lists in one alphabetical series.
