# coaches Source Trail

Research in the registry category coaches can begin with the person-specific authority and bibliographic trails for Jill Ellis. WorldCat can surface relevant works and subjects, while VIAF and the Library of Congress can help disambiguate creators and named persons; none of these search pages establishes an unreviewed category claim.
