Durham's Regulator Bookshop is celebrating its thirtieth year of business in December 2006. Tom Campbell and John Valentine are co-owners. A third partner, Helen Whiting, was also a co-owner from 1982 until she died in 1999. The store started as small storefront shop at 720 Ninth Street. It expanded into the upstairs in 1990, and in 1994, down into the building's basement. The owners attribute their survival as an independent bookshop to devoted community support.
