Each geographic entity has a 5-number sequence that is used to describe subareas from general to specific. For each main number, the subnumbers are:
Classification Web. LC Online call number database. Also has data links to subject headings that correspond to call numbers.
Schedule G: Special Instructions and Tables of Subdivisions for Cartographic Materials. The tables for map call numbers.
Dates in call numbers reflect the "date of situation" or the date the the map data represents (not necessarily the same as date of publication). In addition, a publication date may also be present. See: Date Codes for Maps, a list for determining dates on maps by specific publishers.
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:
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.
Date of Publication
When a item has a history subject Cutter the date in the call number is the same as the date in the publication, distribution, etc. area, since the history cutter itself suggests a general date of situation.
