Marie C. Malaro "A Legal Primer on Managing Museum Collections" (Smithsonian

pp 52-138 cover the accessioning process including acquiring title

for examples galore:

"The Museum Forms Book" edited by Kenneth D. Perry (Texas Association of
Museums/Mountain Plains Museums Association, 1990)

and

The Registrars Committee Forms Clearinghouse
