Obsolete and unofficial extensions
In our first year of implementation, we were using local extensions in fields 591-595 to note items on reserve. We have since moved to using Alma's Course Reserves / Reading lists. These obsolete course reserve notes may still be found in MARC display, but they are not displayed or searchable in Primo VE and may be removed at any time.
In a few cases field 975 has been used for vendor bibs uploaded to electronic collections.
As explained in the document on our 591 note, catalogers may use a local 590 extension if they like.
