Have you seen this?

So… Amazon has all these old books for free in Kindle format.
And all that free software to read Kindle formatted books on your PC/Mac/Mobile device if you do not have a Kindle.

Check this out:

They have quite a few old knitting/stitching books available in Kindle format for free!
Start with the one above and it should recommend others on the “other people who purchased this book also bought” page after you “buy” the free book.

I don’t know that I’ll actually use the books for anything, but I think they’ll be interesting reads.
