SWAN Practice for Managing Serials

Certain serial records are given new records each year due to the frequency of publication or large number of attached items (it does not necessarily mean they are published weekly).  

The base call number of a serial item can follow whichever format your library prefers, but call numbers have rules regarding the construction of the analytic element. 

Each call number has a corresponding shelving key, an internal key used for sorting. When necessary, shelving keys may be modified to correct call number sorting in the item tree. This is particularly useful for serials.
