What reading materials are there for children reading several grade levels beyond "typical" for their age?

Brad's response is very helpful. There are several other resource lists of books I'd like to add to what Brad has already posted.

Hoagie's Gifted is a great online resource for all things gifted, and Carolyn has collected a fanstastic list of reading resources collected from a great many gifted sources.

The Davidson Institute's GT-Cybersource website also has a great collection of reading lists.

I've used Michael Clay Thompson's Language Arts program with my girls and we've ended up reading many of the Classic books he recommends.

There are many more lists, maybe we can add more here.

My kids started reading adult works very early, and it's sometimes been a challenge to prescreen material fast enough to keep up with their voracious appetites. Non-fiction is usually a safe bet, and I do rely on word of mouth as well as prepared reading lists and librarian recommendations. Classics are often great reads, but may contain controversial ideas. Anne of Green Gables, for instance, is a wonderful series, but the books treat Jews poorly. Parents will do well to browse through the books themselves, or ask children if there are any parts that make them uncomfortable, and discuss them. My kids feel comfortable talking about books with me, and understand that each book may have good and bad points.

For reading lists for after the Magic Tree House series books, I've found a few book lists useful for "elementary school years" and am passing these along for those interested:

http://www.carolhurst.com provides reviews of recommended books by grade level. The reviews are a few paragraphs long so there's some detail to help decide if it's what you'd want to select. Note that the Web site is run by an author of children's book, but it seems to be pretty objective and useful.

http://www.gtworld.org provides a few levels of recommended books, with brief annotations, and their recommendations seem pretty on the mark in my experience and which specifically addresses gifted learners.

http://kids.nypl.org/reading/recommended2.cfm?ListID=60 is the NY Public Library annotated list of 100 recommended books.

There are a few books that I thought were particularly good and didn't see on those lists: Mike Venezia's series on "Getting to Know the World's Greatest Artists," for a fun overview of art history and appreciation. Also, Avi's "The Secret School," about a school run by a student, which is an interesting parallel for a homeschooling kid taking ownership of their education. The 3-book series by Joy Hakim on "The Story of Science" is a good one for kids probably beyond approx 3rd grade, and even then probably with a bit of help for a few years after that.

I recognize that this is just a start...

Don't overlook Some of My Best Friends Are Books: Guiding Gifted Readers by Judith Halsted. A new (3rd) edition was published last September. Great Resource.
