The Sarah Buchanan Preston Land Deed collection is a manuscript copy of a land transfer indenture statement for lands in Russell, Tazewell, and Scott counties, Virginia. The land was sold by Preston to John and Edward Fulton of Washington County, Virginia, in 1835.

The collection contains project files and drawings related to more than 1,500 residences, churches, businesses, schools, and community buildings, predominantly in the Roanoke and Southwest Virginia area, designed by Smithey & Boynton, mostly between 1935 and 1957.
