Directory of Special Libraries and Information Centers (DSL)

For three decades, the Directory of Special Libraries and Information Centers (DSL) has identified and described special libraries, resource centers, special collections, and documentation centers located in the United States, Canada, and throughout the world. DSL provides comprehensive and updated and revised information on subject-specific resource collections maintained by government agencies, business, industry, newspapers, educational institutions, nonprofit organizations, and societies in the fields of science and engineering, medicine, law, art, religion, the social sciences, and humanities.

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

Section 1: Scope

As defined for purposes of this directory, special libraries are libraries built around a collection limited by subject matter or form. Functionally, these libraries (which may also have collections of a general nature) operate in support of a special mission or activity chosen by their sponsoring organizations.

The libraries and information centers profiled in DSL contain topics spanning a wide range of interests, including: African Americans, Biotechnology, Climate Change, Environmental Design, Gun Control, International Law, Islam, Military Intelligence, Nuclear Medicine, Psychology, Terrorism, United Nations, Wildlife Conservation, Zoology and many more.

The libraries and information centers in this directory fall within five major categories:

  1. Subject branches, departmental collections, and professional libraries maintained by colleges and universities.
  2. Branches, divisions, departments, and special collections in large public libraries that focus on one particular subject or group of subjects (such as a local history collection).
  3. Company libraries that operate within a framework of a business or industry producing goods, services, or information for profit.
  4. Governmental libraries, including:
    • those serving city departments and state or provincial government;
    • libraries within federal departments and military establishments; and
    • divisions of national libraries.
  5. Libraries supported by nonprofit organizations, including those of:
    • scientific societies;
    • civic, social, and religious organizations;
    • trade associations;
    • historical societies; museums; hospitals; and
    • private collections available for research.

Certain categories of libraries, occasionally found in other listings of special libraries, were omitted. Among these are collections of purely recreational material found in hospitals and prisons. Inclusion in DSL should not be construed as an endorsement of any organization, nor does omission imply a lack of importance.

Section 2: Method of Compilation

The editorial objective for each edition of DSL is complete verification/revision/updating of existing entries and an intensive effort to identify new or previously unlisted facilities. This effort includes not only special surveys, but also email correspondence with nonresponding organizations. The Internet has become a useful updating tool, as many universities and governmental organizations keep extensive and useful websites for their library. As a result, this edition of DSL incorporates thousands of changes in library names, addresses, contact numbers, personal names, and other details.

Section 3: What You'll Find in a DSL Entry and Searchable Fields

Directory of Special Libraries and Information Centers (DSL) contains profiles of libraries. The main method used to store entries is by library 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 library 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.

The Corresponding Advanced Search Index(es) column lists which Advanced Search index to use to search that field.

Field of Information Description Corresponding Advanced Search Index(es)
(State or Country) Name of Organization - Name of Library or Information Center The name of the organization is made up of at least one of the following elements:

  • Name of the library or information center. Independent libraries and centers and those commonly known by a distinctive name are entered directly under the library’s name. Descriptive and memorial names are given as reported. Otherwise, the appropriate generic term is used, e.g., library, archives, collection, information center.
