Last year I bought a czur book scanner that looks kind of like a lamp to try and archive some 100 year old books I had limited access to. The resolution of the camera was so low I ended up balancing my phone on top and getting better images just using it as a light.

I remember reading about Google's book scanner that operated automatically using vacuum pressure to gently flip pages. I'd love to see an open source variety of that.

I'm very interested in getting into archival (getting started this month after a few more conversations).

Your buy button[0] is broken. You're potentially missing out on a few sales due to this.

Is 2x 4GB SD card sufficient for your purposes? I've been quoted 50MB TIFF images as a standard, and a lot of books wouldn't fit without swapping SDs at that size.

Nice to provide hardware hints and designs but geez that is almost the least of it. Cleverest hardware still only gets you a thumb drive full of page images. Now what? There needs to be a software workflow ending with a readable book in PDF, EBOOK or MOBI format, and there are many, many choices to be made along that path.

"In order to turn these raw images into an ebook, the very minimum you need to do is A, you need to rotate them, B you need to crop them down to use the page [?], and C you need to combine them into one document like a PDF... You can do OCR to make it searchable ... color correction... de-skewing, de-warping ..."

I think about Google's scanner project a lot. I wonder if they are still scanning?

I would love if they found a way to offer those books (authors would have to agree) to the world.

If they did, I would forgive them for tracking me all these years.

I'd even put up with ads in the books.

The simplest of which would be to turn the images into a multi page raster PDF, using freely licensed linux based command line tools for PDF generation. Which will of course result in a rather large file size vs doing OCR, but might be the best preservation method for books with illustrations, unusual fonts, catalogs, mixed text and photos, etc.

I am not clear on to what extent the existing workflow does a de-skew of the camera images to deal with page curvature towards the spine.

I think I recall the Internet Archive having an open source design for something similar to this? And other projects which accomplish generally the same idea.
