Main Entries	Added Entries
Titles	Linking Entries
Edition, Imprint, Etc.	Series Added Entries
Physical Description, Etc.	Holdings, Alternate Graphics, Etc.
Series Statements	Locally Defined Fields

Note: Generally, any field containing a "9" (e.g., 049, 910, etc.) is available for local use, such as local call numbers, holdings, or subject headings. Check with your system vendor for further information.
