In 1971, the Collin County Genealogical Society (CCGS) moved its existing genealogy collection to Gladys Harrington Library.  Since that time the collection has continued to grow with the help of gifts, donations, and fund raising programs of the CCGS and the Genealogy Friends of Plano Libraries, Inc.  In late 2007, the collections moved to the basement of the W. O. Haggard, Jr. Library.  Our collection size has doubled since the Fall of 2006.
