The first CDs distributed by MCA sometimes used the older CBS inserts, and catalogue numbers, with a sticker placed over the previous distributor's details and a new barcode, however, the discs themselves have the new catalogue number.

Non-CD cat#s
Initial Anthem vinyl and 8-track releases had the cat# ANR-X-XXXX and 8AN-X-XXXX respectively. The first X indicates the number of discs and the last 4 Xs are the release number.

Later, vinyl was reissued in a budget priced form with the cat# ANR-X-6XX (sometimes ANR-6XX) where the final Xs are the last two digits of the original release. The 8-tracks were replaced with cassettes and the cat# replaced with 4AN as the prefix.
