The TCGHS Library

The Tazewell County Genealogical & Historical Society (TCGHS) was founded in 1978.

For the first nineteen years, the society moved through several donated & rented locations as our collection and membership continued to grow.

Due to the generosity of member Virginia Ehrlicher, a permanent building was purchased in 1997. In her honor, the library was given the name of the Ehrlicher Research Center.

In 2000, an additional donation from member Gladys Wolfer allowed us to upgrade the building's flat roof to a new more easily maintained gable roof.  A further donation by Mrs. Wolfer in 2004 made it possible to further expand our building with a two-story addition.  In her honor, the new addition was named the Wolfer Library Wing.

The Library currently houses our collection of more than 13,000 volumes.  There is also a large research area with tables and chairs for the use of our visitors as well as for monthly meetings and workshops.  The room is equipped with an overhead projector and a public address system.

Our handicapped accessible library is staffed with trained volunteers to guide you through your onsite research. Computers, printers, microfiche & microfilm readers, a copy machine, free Wi-Fi access, and public restrooms are available for our patrons' use.
