The National Instructional Access Center (NIMAC) is a federally-funded, national electronic file repository that makes National Instructional Materials Accessibility Standard (NIMAS) files available for the production of core print instructional materials in specialized formats. Created under IDEA 2004, the NIMAC receives source files in NIMAS format from textbook publishers, and makes these files available for download to Authorized Users in the United States and its territories through an online database. The NIMAC's searchable repository is accessible to anyone interested in locating specific NIMAS files for textbooks and core instructional materials.
