Encyclopedia of Associations: National Organizations of the U.S.

Encyclopedia of Associations (EA) is the only comprehensive source of detailed information concerning nonprofit American membership organizations of national scope. EA is your guide to more than 23,000 organizations in subjects such as Trade, Business, and Commercial; Legal, Governmental, Public Administration, and Military; Cultural; Educational; Veterans', Hereditary, and Patriotic; Athletic and Sports; Fan Clubs, and many more. With its vast listings of associations and professional societies, EA is unsurpassed as a "switchboard," connecting persons needing information to highly qualified sources.

Frequently, a phone call, fax, or letter/e-mail to one of the thousands of organizations formed around a specific interest or objective produces more information faster than research in books, periodicals, and other printed materials.

Organizations often operate with small, volunteer staffs. Many such groups have requested that all written inquiries be accompanied by stamped, self-addressed envelopes. Replies can then be expedited and costs to the organization kept to a minimum.

The remainder of this page is divided into the following sections:

Section 2: Method of Compilation

The editorial objective for each edition of Encyclopedia of Associations is complete verification or updating of existing entries and the identification and description of new or previously unlisted organizations. This intensive effort includes direct contact by correspondence and telephone with non-responding groups.

Section 3: What You'll Find in an EA Entry and Searchable Fields

Encyclopedia of Associations (EA) profiles nonprofit membership organizations in the U.S. The main method used to store entries is by organization name; however, there many ways to find entries, including by Keyword, or by some other specific field of data using Advanced Search (refer to the Corresponding Advanced Search Index(es) column in the table below).

When you search for entries, your search results will show the main fields of data, enough to give you a brief view of the organization profiled. The full entry can be viewed on the entry display page by selecting the entry name from your results list.

Tip: The table below lists the kinds of information you will find in the entries in this eDirectory. Note that not all fields are present in every entry.
