Early on Zylbercweig received support for his project from the Hebrew Actors' Union, which sponsored a 16-page prospectus for the lexicon in 1928; with the Union's help Zylbercweig mailed out a questionnaire to all of its members, the responses to which served as a basis for entries.

[3] Zylbercweig raised money for the publication of these volumes through a number of routes, such as banquets, fundraiser performances, pre-sales, and the sales of his other books.

In the post-War years, however, Zylbercweig understood his mission to be the dissemination of any and all information he could gather, to prevent it being lost to history.
