Frequently asked questions about CHID searches

On this page:

What is CHID?

CHID is a bibliographic database produced by a consortium of Federal health agencies, including the Centers for Disease Control and Prevention and the National Institutes of Health. CHID contains records of hard-to-find literature that is not often referenced in other databases. For example, CHID lists brochures and newsletters by patient-advocacy organizations, booklets by Federal health agencies, and health literature and educational resources for special populations.

What does a record from CHID contain?

CHID records contain bibliographic information. Each item or record is listed in the search alphabetically by the title of the material (TI). Also contained is the author (AU), corporate author (CN), physical description (PD), source of the information (SO), and availability of the information (AV) so that you may contact the appropriate organization to acquire the item. An abstract (AB) briefly describes the item and its subject content.

How often is CHID updated?

New records are added quarterly and current listings are checked regularly to help ensure that entries are up to date and still available from their original sources. The updated database is available at the end of these months: January, April, July, and October.

Are any of the materials in the search available from the NIDCD Information Clearinghouse?

Only if the NIDCD Information Clearinghouse is cited as the source. The full-text materials are available from their respective sources, as noted under availability (AV) for each item in the database.

What should I do if I have questions about my search?
