We've been getting a lot of questions about how the Internet Archive digitizes books.

The other process is several times faster and tries to keep copyright lawyers at bay for some time. Win-win for Amazon etc. …
https://www.404media.co/we-tracked-a-shipment-of-rare-books-it-ended-at-an-amazon-ai-training-facility/@marcel @internetarchive I think actually ripping pages out takes longer than what I'm seeing here. Unless they have some super exact process to machine cut the books open without cutting out any letters, but what I had heard in the past was they employed people to tear them up and feed the pages in.
I mean just look at that video. Flip, press, flip, press, flip, press. It's fast and accurate.
But yes, they destroy them on purpose, which was... kind of my point. They could shred/etc even if they preserved them. Though I'm not clear why they can't give them to a charity or something (tax break!)
BTW you shared a paywall article. I've already heard about that though and was specifically referring to it as an example, but if I hadn't that wouldn't be a particularly helpful link...

The short answer: page by page, by hand.
You may remember our viral 2021 video of Eliza Zhang scanning a book. That's still how we do it.
Meet Eliza, and learn how we scan books: https://blog.archive.org/2021/02/09/meet-eliza-zhang-book-scanner-and-viral-video-star/
@internetarchive@mastodon.archive.org As someone who used to work in a print shop, and has done my share scanning stuff from books, I desperately wish we'd had a scanner like that for the book copy jobs I did. Laying books open on a flatbed scanner is so tedious, and the repetitive motion of having to pick up the book to turn the page between each scan is exhausting. This would still be tedious, but a little easier only having to turn the page.
You can tell this machine was designed by someone with care for both the book and the operator. -
@jj @gloriouscow @internetarchive my issue is when looking at the metadata there is an excessive amount of images to process.
@Thorsted @gloriouscow @internetarchive this is not entirely my experience. for my
current work i'm looking at a bunch of (IA) MRC-encoded documents.pdfimagesdumps the foreground/background/masks which gives you very clean pages of text (as images) upon inverting the masks. it's three images per page but this is Finewhat i do find difficult to do though is recovering inline images, since MRC (or at least IA's use of it) does not attempt to extract those at all

@jj @Thorsted @internetarchive I just know I've never seen a jpeg change a letter
@gloriouscow @Thorsted @internetarchive fair point!

From the descriptions I've seen, I imagine, they just cut the spine abd a few Millimeters off. There is some 2 cm of leeway there, exact cutting not required.A quick product search revealed scanners with 3 sheets per second, no human operator required. From a "scan things fast and cheap" standpoint, that is much "better" than what's done here. (Of course, the IA approach has several benefits to the AI approach, but I don't need to point them out here.)

@gloriouscow @internetarchive Thanks. OCR should only be used as invisible 2nd layer. pdf/A shouldn't allow this. Version 1 had recognition errors which were corrected in v2. 3 and 4 allow for extra content, which is not advisable since it's unclear if it's accessible in the future. 2a should be choosen because of the accessibility requirement. Screen readers can read them properly.
@Hammerwell @gloriouscow @internetarchive OK, well, the file you are linking to (In https://archive.org/details/PCMAG) was not scanned by Internet Archive. It was uploaded by a user 5 years ago, using whatever PDF approach they decided to take, or, more likely, was taken by someone THEY duplicated the scans from.
Here's another non-IA-done scan, with proper work.

Sadly IA has not released design docs for their upgraded version, despite being asked repeatedly.

@Hammerwell @gloriouscow @internetarchive And here is the .TIFF file that PDF was generated from.

@Hammerwell @gloriouscow @internetarchive So in terms of "stop using MRC in PDFs", I guess the answer is "Done"

@internetarchive surely any book printed in the last 35 Years was made digitally in the first place? Do publishers really delete those? Or is there some weird copyright loophole for scanning a printed version?

There's no need to destroy books in the process. The techbros just want to make it as cheap as possible, with the added benefit of taking books out of circulation so people need digital technology to access them. It's a retreat from the egalitarian printed book, back into a world where information is controlled by the wealthy. The reverse of progress.
