Information is then added to Alexandria Archaeology's register of sites in the City.

The City of Alexandria has laws that protect archaeological sites so that information may be recovered before they are destroyed by development.

Archaeologists in Alexandria view the entire City as an archaeological site.

A newspaper such as The Alexandria Gazette, first published in 1784, is an excellent source for local history.

Deeds, tax records, census records, photographs, diaries and maps are among the best primary sources for learning about the history of Alexandria sites.

Some notable places in Alexandria where archaeologists and historians conduct research are: the Alexandria Library, Special Collections at 717 Queen Street, which stores books, documents and microfilm on Alexandria and Virginia history; The Alexandria Court House at 520 King Street which holds legal records including deeds and wills, and the City Clerk's Office in City Hall, 301 King Street where City Council Minutes are kept.

Archaeologists make accurate maps of each site prior to excavation.

A datum point, or point of reference from a United States Geological Survey benchmark, is established, and measurements are taken from that point.

A grid is established over the site with string held by large nails or stakes.Secondary sources, such as history books, can be useful if they are accurate as stories or rumors that are loosely based on fact become embellished as they are passed from generation to generation.It is important for archaeologists and historians to distinguish between fact, opinion and legend.Stratigraphy is the study of the strata, or soil layers, of an archaeological site.The effects of human and natural actions over a long period of time cause visible changes in the color and texture of the soil.Sometimes sites are discovered by chance by home-owners who find artifacts, building foundations, abandoned wells or privies in basements and backyards.
