Display of Enumeration

Defining enumeration determines the display of the enumeration—is it Vol 10, No. 2 or Vol X, Part II?—and when each part of the enumeration increments—Does the issue number start over at one at the beginning of each new year? Does the volume number increment by one at the start of each new year? Or does it change in the middle of the calendar year?

To set up enumeration, you must first determine how many “levels” a title’s enumeration has—a “level” referring to each individual component of the enumeration. Levels can include volume, issue, part, pages, and so forth. You then define the parameters of each level in its own group entry so that when you finish, you would have as many group entries as the title has enumeration levels.

This illustration shows the enumeration levels of a title with issues that are published quarterly:

Related levels make up an enumeration group. In the example above, the volume and number levels make up group 1, because the volume level changes when the number level reaches a designated number; that is, the volume level depends on the number level. The issue level makes up its own group since it increases independently from the volume and number levels.

Both enumeration groups and levels start from the most general or all‑encompassing portion—group 1 and level 1. For the example above, the volume would be level 1 of group 1; the issue level would be level 1 of group 2.
