Research Policy

Visiting a Depository

Researchers may visit an IRAD depository and examine the records that are available. The seven IRAD depositories are open Monday through Friday. Depositories are closed on Saturdays and Sundays, some state or federal holidays, and any weekdays the university libraries are closed. Hours may be reduced in June and July. Researchers are urged to call before planning a visit to a depository.


Requesting a Search

IRAD welcomes mail and telephone requests from researchers interested in genealogy and local history. In order for depository staff to conduct a search of the IRAD holdings, researchers should provide the following information:


  • The full names of the persons they are researching
  • The approximate year when these persons are expected to appear in the records
  • The county which created the records
  • Record titles/types to search

Include any additional information that may assist in locating the person or information requested (such as township or precinct for searches of tax and election records).

Researchers also are asked to limit requests to two (2) names at a time and to wait for a response to one request before submitting additional requests. Inquiries should be sent directly to:

The research services of the IRAD system are provided at no charge. Therefore, when requesting information by mail, a self-addressed, stamped envelope is not necessary. However, there will be a photocopy fee, for which you will be billed. Unless an expenditure limit is set in advance by the researcher, authorization to produce photocopies will be requested for billings that exceed $5.
