The American Association of Retired Persons (AARP) has created a resource that "describes clearinghouses, databases, libraries, directories, statistical resources, bibliographies and reading lists, texts, and Web “metasites” focusing on aging or closely allied subjects." The information comes from more than 20 countries. This is a wonderful resource for public health practitioners as well as librarians as you can search by subject, country or region, or by type and language.

It is located at <http://research.aarp.org/general/agesource_home.html>.
