The (London) Times -- founded in 1785 as The Daily Universal Register, renamed The Times in 1788 and now owned by Rupert Murdoch -- has digitized its newspaper archives:

* Every issue of The Times published between 1785-1985, digitally scanned and fully searchable
* Click and drag navigation
* Save, print, e-mail favourite articles
* 150 topic pages, plus magnificent archive photo galleries

And it's free, for now. (Registration seems to have kicked in since I wrote this earlier today and forgot to publish it. Some of these links may work, others may throw you the speedbump.)

It would have been spectacular if reports of the American Revolution had existed, but we'll have to settle instead for the French Revolution:

Excerpt (what looks like an 'f' is actually an "s"; "ci-devant" means "from before," the old regime.):

Later, but special, an August 13, 1868 review of Lewis Carroll's Alice's Adventures in Wonderland.

Have at while it's still free.
