45 CFR § 1100.4 - Current index.
The National Endowment for the Arts shall maintain and make available for public inspection and copying a current index providing identifying information for the public as to any matter which is issued, adopted, or promulgated and which is required to be made available pursuant to 5 U.S.C. 552(a)(1) and (2). Publication and distribution of such indices has been determined by the Foundation to be unnecessary and impracticable. The indices will be provided upon request at a cost not to exceed the direct cost of the duplication.
