If you library uses prefixes and/or suffixes in call numbers, you can build a standard list, which will be displayed as dropdown lists when creating/editing call number record.
This is how it looks on the call number creating/editing screen.
To create a call number prefix or suffix, go to Administration → Server Administration- > Call Number Prefix or Call Number Suffix.
To view the group penalty thresholds for your library enter your library code into the Library filter. Multi-branch libraries can enter the system and then check the box to display the descendants.
Click Save.
To edit or delete a prefix/suffix, check the record, and then click Edit Selected or Delete Selected.
Call Number Prefix/Suffix created here are different from Label Prefix/Suffix created on Copy Location Editor. The former are displayed as part of call number in OPAC, while the latter are on printed labels only.
