+Prevent bibliographic records from having attached copies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+To enable libraries to designate specific sets of records as only for use
+as electronic resources, it is possible to configure a bibliographic source
+such that physical copies or MFHD records may not be attached to records
+from that source. The 'config.bib_source' table now includes a new Boolean
+column, 'can_have_copies', that controls this behavior. If 'can_have_copies'
+for a given bibliographic source is 'TRUE', then the staff client will prevent
+a cataloger from adding volumes or MFHD records to records belonging to that
+source.
