TGM I editors accept proposals for new terms or changes to existing terms. Proposals for new terms are considered, if their application is clear and general enough to be useful in indexing collections of historical images. A proposal form that can be printed or downloaded is available below.

If you are submitting a proposal for the first time, you may wish to contact us by email with questions: [email protected]. Proposals may be submitted by email (attach completed form(s)) or fax: 202-707-6647.

Proposals are reviewed regularly, but it may take two to three months for proposals to be reflected in the online thesaurus.
