Sagebrush Corporation is the former name for Tandem Library Group, an American company based in Topeka, Kansas. While known as Sagebrush Corporation, the company produced library automation software, sold books under the "Sagebrush Education Resources" name, and provided data services, including retrospective conversions, to libraries and publishers. In July 2006, it was announced that Follett Software had purchased Sagebrush's complete library automation software product line. As a result, Sagebrush Library Automation currently operates as a subsidiary of Follett Software Company. The Sagebrush Books and Library Services divisions operate as an independent company under the name Tandem Library Group, the divisions of which are named Tandem Library Books and Tandem Library Services. Sagebrush's Viewpoint division operates under a separate company.
The company entered the library automation software market in 1998 with the acquisition of Nichols Advanced Technologies Inc. and its library automation products Athena and MOLLI, originally released in 1994 and 1985, respectively. In 1999 they acquired Winnebago Software, and that company's Spectrum library automation package, originally released in 1997 replacing Winnebago's earlier products CIRC/CAT and LCS dating back to 1982. The company's newest product is InfoCentre, which is intended to be a replacement for both Athena and Spectrum.
