Date

Date of situation:

Except for an item classed as history, in subject Cutter category S, the date in the call number represents the date of information or situation, not the date of publication. Examples:

If there is no indication of the date of situation on the item, it is usually assumed to be the same as the publication date.

A date of situation cited on an item is used in the call number, unless there is good evidence that the date is wrong. Example:

Many maps of Israel have this main title, or a similar title. It is not a date of situation for the map generally, but only a date of situation for the cease-fire lines. This type of determination can only be made with some experience in cataloging materials for the area.

The year of the date of information given on a work is used as the year in the call number, even if the information date is the first or last day of the year. Examples:

When the date in the call number differs from the publication date, the cataloging record must contain some justification for the discrepancy, whether in the title, edition statement, statement of responsibility, notes, etc.

When the date of situation is a BC date, the call number date is transcribed simply as BC. Example:

When the date in the call number is based on a range of dates from the edition or the publication, distribution, etc. area, the earlier date is used in the call number. Examples:

When the date in the call number is based on a range of dates for information depicted, the later date is used in the call number. Examples:

If a map has been described as From ... or Appears in ... an atlas the date of information for the call number is the date of information, if any, form the item in hand rather than from the atlas.

Forest Service Maps:

The date of situation of a U.S. Forest Service map is the latest date on the item, regardless of whether this date is the date of publication, revision, compilation, etc. Except do not use a printing date on a U.S. Forest Service map for a date of situation. The printing date on these maps can be used in the imprint (e.g., (1989 printing)) and/or as a quoted note.
