Serial call number decisions

Updated 2019

Cataloging situation	Instructions
When cataloging a title change with continuous numbering* and the earlier title's call number is LC:	Use the same call number on the new title.
When cataloging a title change with continuous numbering* and the earlier title's call number is an LC call number that includes an internal "x":	Drop the internal "x" when assigning the new call number.
When cataloging a title change with continuous numbering* and the earlier title's call number is Richardson:	Assign an LC call number to the new title.
When cataloging a title change with continuous numbering* and we do not have the earlier title:	Use the LC call number from the earlier title, if available.
When cataloging the earlier title of a continuation (with continuous numbering*) and the library has the later title with a cutter number for that later title:	Use the same cutter when cataloging the earlier title.
When cataloging a title change that begins with a new sequence of numbering**:	Assign a new LC call number whether or not the previous title was classified in Richardson or LC. If the previous title had an LC call number, the new LC call number assigned should preferably be close to the old LC call number.
If a title splits into parts:	Each part will get a new LC call number, whether or not the previous title was classified in Richardson or LC. The new call numbers assigned should preferably be close to the old LC call number.
If separate titles unite to form a new title:	The new title will get a new LC call number.
In a title change situation, when a new title changes from an oversize to regular size or vice versa:	Drop or add the oversize designation when assigning the new call number.
For a microfilm or microfiche serial title change:	Keep the same accession number for the new title.
A serial supplement to a serial will often get the same LC call number as the serial + the word "Suppl." (e.g. Scottish literary journal; and, Scottish literary journal. Supplement). If the serial supplement has a totally different title, however, it is usually classified for its content.	--
No dates are added to serial call numbers; dates may be used as the designator for individual issues of a serial.	--
When adding a copy for another location (AC) to a serial with a Richardson call number:	Assign an LC call number for the added copy.
When adding a copy for another location (AC) to a serial with an LC call number that included an internal "x":	Do not include the internal "x" when assigning the call number for the AC.
When adding a copy for the same location (ACX):	Use the same call number as the first copy, whether Richardson or LC.
Not all serials are assigned call numbers; e.g. Brief cataloging.	--

* Continuous numbering is taken to include also serials with date only as an adding element. It also includes cases where either the numerical or chronological designation is dropped or added with the new title as long as it does not start over with vol./no. 1.

**"new series", "second series", etc. are usually NOT considered to be a new sequence of numbering.
