The mission and sole purpose of the Groton Historical Commission is to identify, document and catalogue all of the Town's historic assets and to help preserve the historic character of Groton for future generations. In 2005 the Commission embarked on a multi segmented, multi year Community-Wide Preservation Project, which when completed will produce a complete historic survey of the Town of Groton identifying, documenting and cataloguing all of the town's historic assets.

The surveys, completed by architectural historian Sanford Johnson for the Groton Historical Commission, were published in three segments, with each segment divided into one to five volumes. These surveys have been registered with the Massachusetts Historical Commission.

In summary, the historic architecture surveys cover:

• 251 architectural properties, primarily houses, but also the library, 6 churches, 5 school buildings, several commercial buildings, and various meeting halls (e.g., Groton Grange, Sqannacook Hall, Odd Fellows Hall, Bigelow Hall)
• 8 historic areas, including Town Center, Farmers Row, West Groton, Groton School, Lawrence Academy, Country Day School, Surrenden Farms (now re-named General Field), and Hollingsworth & Vose Industrial Area
• 2 cemeteries - Old Burying Ground, Groton Cemetery
• Fitch's Bridge
• Groton Soapstone Quarry
• Prescott Milestone

Segment 1 (2006), 5 volumes, covers many of the oldest buildings and neighborhoods in town. Segment 2 (2007), 5 volumes, covers many buildings constructed up to roughly the middle of the 19th century, and Segment 3 (2008), 3 volumes, includes many more structures dating from the later 19th and early 20th centuries. In each segment, surveys for individual buildings are arranged by their street address in alpha-numeric order.
