Time travel + Going into books

Two book questions for you today inspired by my desire to avoid the stuff I need to be doing:

1. I love time travel books and am always interested in recommendations in general, but right now I am specifically looking for books where characters from the past come forward to the (relative) present. Can anybody think of any?

2. I got way too much guilty pleasure out of the recent BBC miniseries Lost in Austen. It made me want to try other books (or other media?) that involve characters going into books or book characters coming out of them. I can only think of three others:

a. The Thursday Next series by Jasper Fforde (meh)
b. Seducing Mr. Darcy by Gwyn Cready (appallingly awful)
c. Travel Far, Pay No Fare by Anne Lindbergh (absolutely delightful and sadly under-recognized YA book that I heartily recommend to everybody)

I know there must be others. Can you help me find them?
