One of my contributions to Project Gutenberg was proofreeading and formatting of the Radio Amateur's Handbook by Frederick Collins, 1922. You can read the entire book here, including all illustrations.

I recently borrowed this book from a friend, and found it very useful. I was already a fairly fast reader, but I had never investigated "speed reading".

I found that by following these techniques, not only did I read faster, but my comprehension improved. The book covers speed reading techniques and also related improvements in study skills for students.

Oxford Helps for the Study of the Bible is a reference work from the late 1800s on the Bible. I scanned it and contributed it to the Christian Classics Ethereal Library.

You can help edit and proofread it.
