This finding aid was produced with generous financial support from the National Historical Publications and Records Commission.

Scope and Contents

The Metal Parts Collections consists of original masters, mothers and stampers from several donations, including parts for issues from Music Library Recordings, the Sir Thomas Beecham Society and the International Record Collectors Club. Metal parts are used in the production of phonograph records, beginning with the nickel-plated master. Many mothers can be derived from one master, and many stampers from one mother. In some cases stampers produced later document the longevity of certain recordings. However, there are not necessarily masters, mothers and stampers for each release. The Archive maintains a spreadsheet with a full listing of matrix/issue numbers, dates, and other information.
