From NLM:
The U.S. National Library of Medicine (NLM), in collaboration with Boston University School of Medicine is pleased to announce the launch of the Health Literacy Tool Shed
The Health Literacy Tool Shed is a free, user-friendly, unique, curated online database of more than 100 empirically validated health literacy instruments. The Tool Shed serves as an interactive, one-stop shop where researchers use provided filters to select a health literacy research instrument.
The Health Literacy Tool Shed provides background information about each instrument and enables users to compare them.

Each instrument within the Health Literacy Tool Shed is peer reviewed by health literacy research experts including: Michael Paasche-Orlow, M.D., M.P.H., Boston University School of Medicine; and Lauren McCormack, Ph.D., M.S.P.H., RTI International. The selected instruments vary in terms of user accessibility and cost, as mandated by the original investigator.
