Numbers 4, 5, 6, 12, and 13 are not required or given in the above entry, but are here inserted to make the table complete. With the exception of numbers 1 to 4, this order may be varied at will, but only at the outset, as whatever order is decided upon must afterwards be adhered to. The following statement of the order given in some of the rules is of interest in this connection, and will be helpful:—

British Museum order under its Rules (3, 16-22):

1, Author. 2, Title. 3, Edition. 4, Number of parts or volumes or numbered pages if a single volume. 5, Place of printing or publication and printer's name (if necessary). 6, Date. 7, Size. 8, Press mark. 9, Note, if required.

Cutter's Rules:

1, Author. 2, Title. 3, Edition. 4, Place of publication. 5, Publisher's name. 6, Date. 7, Number of volumes or number of pages, illustrations, etc. 8, Size. 9, Notes of contents.

Library Association and American Library Association Rules:

1, Author. 2, Title. 3, Additions to title, if any. 4, Edition. 5, Place of publication. 6, Publisher's name. 7, Place of printing, if given. 8, Date. 9, Volumes or pages, illustrations, etc. 10, Size. 11, Series. 12, Contents and notes.

For most libraries the information can be satisfactorily curtailed and limited to the following:—

1, Author. 2, Title. 3, Edition. 4, Date. 5, Press mark. 6, Contents or annotations. To these may be added, between 3 and 4, an abbreviation telling if the book is illustrated, as "illus.", instead of giving the collation in full.
