With the U.S. dating back to 1776, it's easy to forget how old places like Rhode Island are. The Rhode Island State archives hold documents dating back to 1638. But as a small state, the archives also have a small digital presence.
Rhode Island's Virtual Archives page highlights some featured items and exhibits, but for the full list of each, visit Exhibits and/or
Items (How small is the collection? 506 items!).
The State Library has some online historical content -- more write-ups than archives -- including:
The Rhode Island Historical Society has some interesting content posted, including the mysteriously named exhibit on Brunoniana.
Speaking of Brunoniana, Brown University hosts several online archive collections, though more with an academic than a strictly Rhode Island focus.
And last but not least, the unusual Rhode Island Art in Ruins site offers up an intriguing collection of things (mostly buildings) that were once quite beautiful, and may still be so, though they are now in a state of decay.
