National Instructional Materials Access Center

Created by IDEA 2004, the NIMAC is a federally-funded, searchable online repository of source files for K-12 instructional materials. We receive files in the XML-based NIMAS (National Instructional Materials Accessibility Standard) format, and states use these materials in the production of accessible formats such as braille, large print, and digital text. The NIMAC currently has over 74,000 files from more than 160 publishers.
