This part describes cataloging in Evergreen.
The tag tables for the web staff client MARC editor are
stored in the database.  The tag-table
service has the following features:
- 
specifies whether (sub)fields are optional or mandatory
- 
specifies whether (sub)fields are repeatable or not
- 
a coded value map can be associated with a subfield to
  establish a controlled vocabulary for that subfield
- 
MARC field and subfield definitions can be overridden
  by institutions further down in the organizational unit
  hierarchy.  This allows, for example, a library to specify
  definitions for local MARC tags.
- 
values supplied by the tag-table service are used to
  populate values in context menus in the web staff client
  MARC editor.
MARC Tag Tables can be found under Administration → Server Administration → MARC Tag Tables.
