A gateway and an archive of numerous articles on New York history, this site "focuses a particularly long lens on the early history of political and economic events, panics, riots and other related matters affecting or contributing to New York City's development and growth." Its main feature is the New York state and New York City directories. (The U.S. directory is currently unavailable.) The New York state directory offers more than 700 links and more than 60 articles organized under 21 topics that include the arts, cities and counties, ethnic groups, military, societies and associations, transportation, women and their professions, and worship.

The New York City directory offers more than 5,200 links and more than 700 articles organized under 58 topics that include architecture, the arts, business matters, city government, clubs and societies, crime and punishment, education, ethnic groups, 5th Avenue, Harlem, immigration, New York City panics, real estate, temperance and prohibition, and Wall Street. The visitor can search the entire site or each directory by keyword. This site is a good starting point for researching the history of New York. It should also be useful for literary scholars, writers, and historical societies.

An adjunct site to a PBS "Frontline" program exploring the claim that Thomas Jefferson fathered at least one and maybe all of the children of his slave, Sally Hemmings. This view is supported by DNA testing and believed valid by a consensus of historians and experts. The site presents ten essays ranging from 2,000 to 5,000 words in length by prominent historians and other scholars—including Joseph Ellis, Annette Gordon-Reed, Philip D. Morgan, Jack Rakove, and Gordon Woods—on the controversy, its historical background and significance, interracial sex in the antebellum Chesapeake region, Jefferson's legacy, and America's mixed-race heritage. The site also provides accounts by four Monticello slaves and the chief overseer; four video segments, from seven to nine minutes each; transcripts of interviews with Ellis, Gordon-Reed, Dr. Eugene Foster, who designed and carried out the testing, and Lucia Cinder Stanton, from the Thomas Jefferson Memorial Foundation; and links to a clearinghouse for information that argues against the claim.
