The virtual collections in CJH Digital Collections are based on
type (the lab uses genre terms to build the “collections by type”
browsing hierarchy, such as “children’s books,” “drawings,”
“photographs,” etc.), repository (the Center and its five partners), and
provenance (title of a collection). Most recent research recommends
organization by subject (Schaffner, 2009). The lab has begun this type
of organization for a selected set of photographs from YIVO (subjects
are Holocaust, political life, Yiddish theatre and others).
