The Edward H. Nabb Research Center has historical information online about the Delmarva (Delaware, Maryland, Virginia) peninsula.
They also have a description of their in-house collections which are extensive.
“Our non-circulating library contains books, serials, archival and artifact collections relating to United States history, the greater Chesapeake region and the Delmarva Peninsula. Our extensive primary and secondary regional archival collection contains family histories, correspondence, photographs, manuscripts, ledgers, diaries, local business and organizational records, maps, newspapers, land surveys, oral histories and rare books. Included in our microfilm collection are governmental and church records pertaining mainly to Somerset, Worcester, Dorchester and Wicomico counties in Maryland; Accomack and Northampton counties in Virginia; and Sussex County in Delaware. Archaeological materials, furniture, vintage clothing and coverlets, household items, tools, and military memorabilia comprise a portion of our artifact collection and are used for classroom instruction and exhibits. One of our best resources is the specialized expertise of the Nabb Research Center staff.”
