Court of Appeals for the Seventh Circuit July 15, 1985, 84-2301 (Rockford Map Publishers, Inc. v. Directory Service Company of Colorado, Inc. And Frances A. Anderson)

EASTERBROOK, Circuit Judge.

A plat map shows the location, size, and ownership of parcels of land. Rockford Map Publishers makes plat maps of rural counties. They are useful to local residents and to sellers of farm equipment, who can learn the identities and needs of potential customers. Doubtless they have other uses as well.
