Before Jan. 1, 2017 the record is one snapshot per annual CFR edition, revised as of October 1. This is the 1996 edition's wording. An amendment that took effect between Oct. 1, 1997 and Oct. 1, 1997 would not appear until the next edition, so check the citations below and the Federal Register for exact effective dates. govinfo does not publish the 1997 edition of Parts 300–399 in machine-readable form, so the 1996 text is shown for that year.
