The 946 $m is used to mark records within a collection so that the records can be easily retrieved. It is used primarily to tag records for individual books with e-books packages, but has also been used for other project collections. To find all the records for a particular collection in Aleph, use the keyword index WPI (project identifier); case does not matter.
