The National Instructional Materials Accessibility Center (NIMAC), established in Louisville, Kentucky, receives and catalogs publishers' electronic files of print instructional materials in the NIMAS format. The center then provides these standardized source files to those who have been authorized to obtain them in order to produce textbooks and other core print instructional materials for blind, visually impaired, and print-disabled students.

The Table of State Coordination is a summary table indicating whether states have selected to coordinate with the NIMAC. Note that all fifty states and the District of Columbia have indicated that they plan to coordinate with the NIMAC and updates will be posted when each Annual State Application under Part B of IDEA 2004 is amended.

The Publishers & Conversion Houses Home Page is an annotated list of metadata fields required by the NIMAC as part of NIMAS fileset submission to the national repository. It includes notes and examples. Note that NIMAC metadata requirements are in addition to the requirements of the NIMAS 1.1 specification for filesets. Includes a full version sample OPF file with NIMAC metadata, NIMAS metadata, history, and comments. (Go to Exemplar 9 to view a sample NIMAC OPF file in XML and in Word without history and comments or to download the history and comments as a separate Word document.)

Authorized Users (AUs)

Designating AUs explains who coordinates with the NIMAC, what they need to do, and how authorized users of the NIMAC Repository are designated.

The Authorized User Page provides instructions for an Authorized User selected by an SEA to register with the NIMAC using the Limitation-of-Use Agreement (LUA).

Forms and Agreements

NIMAC Coordination Agreement: Authorized representatives of educational agencies that have chosen to coordinate with the NIMAC must submit this coordination agreement to the Repository in order to obtain filesets.

The NIMAC Limitation-of-Use Agreement (LUA) is required of authorized users of the Repository (contact the NIMAC for more information).

The State Coordination Registration Process provides instructions for SEA NIMAS Coordinator or other SEA representative to complete and submit the NIMAC Coordination Agreement.


The NIMAC FAQ provides additional information about the NIMAC.

The Accessible Media Producers (AMPs) FAQ explains AMPs' role in the NIMAC in a frequently asked questions format.
