A simple "1-click" javascript approach to downloading a scanned book from archive.org to read at your leisure on the device of your choosing w/out having to manually screenshot every pages of the book by hand. In short it's a glorified "Save Image As..." approach but consolidated down to "1 click". BTW there may be a much better option than this out there - I just built this as an autistic project to see if it would work.
By using this script you agree to delete all book files/images after your 1 hour or 14 days is up! I don't support using this script for any other use cases. After all, none of us have ever kept a library book past it's return date, right?
- Scanned Books Only: This only works on "scanned" books where each page is an image file. This means A) you won't be able search the text of the book and B) the book file size will be tens of megabytes not kilobytes like an EPUB/etc. Given the above always try to find the book in text format first (epub, etc) before using this method.
- Compatibility: As of 11/2021 I've tested this on a few books w/no problems so it seems pretty stable but if someone finds a book that doesn't work w/it LMK in comments. It's very possible (likely?) at some point archive.org will change something that either requires some adjustments to this script and/or makes this approach no longer possible. Feel free to recommend tweaks or fixes if anyone has any suggestions btw.
- Borrowed and?: I've only tested this for "Borrowed" books but I suppose you could use on Free books too - although normally those already offer a PDF download so not really a reason to do that.
- Support: This is just a basic javascript thing so there's no real danger here but I can't/don't provide any support if this doesn't work for you and/or your browser crashes while trying it.
- Create a bookmarklet in your browser using the code below via https://mrcoles.com/bookmarklet/
- Go to archive.org and "Borrow" the book for 1 hour or 14 days (only tested with the 1 hour)
- Once the borrowed book page reloads click zoom icon to zoom into the 1st page of book at least 2 times (otherwise you'll get low-res version of book images)
- Write down or make a mental note of how many pages the book has
- Use browser's "Inspect Element" on first page of book to find the page image URL and right-click to "open link" in a new tab.
- Once on the new tab looking at the book's 1st page image, click the bookmarklet button made in step 1 and type in the number of pages the book has that you noted in step 4. Tip: Add 5-10 more pages than the book has just in case the covers/final pages of the book actually add up to a higher number.
- As soon as you click 'OK' after entering the page count watch for the browser's "Allow Multiple Downloads from this Site" type message in your browser and click 'Accept' or whatever. Otherwise the process will fail. Some browsers may not do this - so disregard if this isn't an issue w/your browser.
- Wait for the process to finish - a 300 page book takes around 3-5 minutes. Note: You can minimize the browser tab/window while the pages are downloading.
- Once all pages have been downloaded an "alert" message will popup when the pages have all been downloaded.
- At this point you'll have a bunch of book page images in your Downloads folder like mybookwhatever_000.jpg, mybookwhatever_001.jpg etc.
- If you want to make a PDF of the pages go to https://tools.pdf24.org/en/images-to-pdf and drag all these images into the upload area. When the images are uploading click the "A-Z sort" button at the bottom of the page to make sure the pages sort by filename.
- Click the "Create PDF" button when it's ready and download the PDF when it's done.
- Now you can enjoy reading the book at your leisure, wherever you want without having to wait for the annoying page load times of archive.org, etc!
