The Museum of the City of New York has released a treasure trove of old New York City photographs on its website. Sadly, perusing them isn't very easy over there—or as Kottke noted, "the interface is a little hinky." You've probably seen photographs from their featured photographers before (who include Berenice Abbott and Jacob Riis)—but there were some images that were even new to us, click through to check out some of them.
UPDATE: A rep for the museum tells us, "This is intended to be the soft launch and we’re planning a period of time during which we collect feedback. We’ll re-launch a new version of the database sometime early in the new year. It’s a work in progress and people can send comments on the site to firstname.lastname@example.org."
