Text: ATC complains that the district court failed to address the claim that its Numbering System Manual was protected by copyright. This is true, but understandable. Despite the rather grandiose title ATC gives this document, presumably with the intention of evoking Baker v. Selden’s holding that an explanation of how to use an otherwise unprotected system may itself be protected, see 101 U.S. 99, 104 (1880), the materials ATC describes in this way are nothing more than an index-like list of all the part numbers and No. 03-6505 ATC Distribution Group, Inc. v. Whatever It Takes, et al. Page 10 categories of parts in the catalog, which ATC acknowledges to be a quick reference guide for ATC employees. This index does not explain the parts numbering system, but simply compiles the list of parts numbers in an unimaginative way. As such, the manual is no more copyrightable than the catalog for which it serves as a quick reference.
