Contents Notes - Insets:

A separate map positioned within the border or neat line of the item being described is an inset.

When constructing a simple contents note, only maps within the borders of the "main map" are identified as inserts. In most instances, insets within the borders of another inset or an ancillary map are not mentioned in the bibliographic description.

The subject or content of all insets is described, if at all possible, either by using descriptive terms or quoted titles.

When individual insets are too numerous to mention individually, groups of insets may be described by using generic terms such as local maps, local route maps, etc. Except subject insets are described individually.

When the insets are numerous or unimportant enough that it is not necessary to distinguish among the various insets and types of insets, simply count the insets and record the number in a contents note as [number] insets. Example:

However, when certain insets are sufficiently important to be mentioned either individually or as a group or type, the remaining nondescript insets that belong to no specific type are described simply as other or additional insets. Examples:

When describing insets, a note should be as specific as possible in the description of map contents. Grouping of types of individual insets is generally done only when a more specific note would be complex, confusing , or unreadable. Examples:

The presence of an index to an inset is usually mentioned. Example:
