SACO Music Funnel
The SACO Music Funnel Project was formed in 2010 and falls under the Library of Congress Cooperative
Cataloging Program known as SACO (Subject Authority Cooperative Program). Members of the Music
Library Association (MLA) were charter members of the SACO Music Funnel Project. The goal of the
project is to promote and facilitate the creation of medium of performance terms and of subject
authorities relating to the cataloging of notated music, musical sound recordings, and works about
The funnel project provides a framework for proposing new subject headings for inclusion in Library of
Congress Subject Headings (LCSH), new classification numbers for Library of Congress Classification
(LCC), new medium of performance terms for the Library of Congress Medium of Performance Thesaurus
for Music (LCMPT), and eventually music terms for the Library of Congress Genre/Form Thesaurus for
Library and Archival Materials (LCGFT). All Music Funnel proposals are submitted under the institution
code for the funnel: CaStSMF. There are no membership requirements; all those cataloging music
resources are welcome to submit proposals. The aim is to assist you as much as possible in getting your
proposal through the submission process and approved.
Currently, the Funnel accepts proposals for LCSH music headings and LCMPT terms only. No new music
terms are being accepted for the Library of Congress Genre/Form thesaurus (LCGFT) at this time since
the initial vocabulary is still being finalized. Once open for new proposals, the Music Funnel will also
support catalogers in adding to that vocabulary.
While consulting with the SACO Music Funnel is not mandatory for LCSH headings, all new terms for
LCMPT must be submitted through the SACO Music Funnel (unless you are LC cataloging staff).
Submissions may be sent the Coordinator (currently Nancy Lorimer
, Stanford University) through email, either including the proposal in the body of the email or using
the proposal forms provided for guidance.
