Bookmarklet to add download links for audiobooks in the Overdrive loans page

bookmarklet.js

/* 1. Paste this entire gist over at https://mrcoles.com/bookmarklet/ to generate a bookmarklet */
/* 2. Use a meaningful Name like: 🎧 📖 Links */
/* 3. Drag the generated bookmarklet link to your Bookmarks Toolbar. */
/* 4. Click on the bookmarklet when you're on the Overdrive loan page, e.g. https://yourlibrary.overdrive.com/account/loans */
/* 5. The "Download MP3 audiobook" link should appear like it used to. */


$('a[data-format-id="audiobook-overdrive"]').each(function() {
    var listenBtn = $(this);
    if (listenBtn.hasClass('script-added')) {
        listenBtn.remove();
        return;
    }
    var dlBtn = listenBtn.clone();
    dlBtn.attr('class', 'loan-button-nonkindle button radius primary downloadButton script-added');
    dlBtn.attr('href', dlBtn.attr('href').replace('/audiobook-overdrive/', '/audiobook-mp3/'));
    dlBtn.html('<b>Download</b><br/><span class="dl-text">MP3 audiobook</span>');
    dlBtn.attr('target', '');
    listenBtn.parent().append(dlBtn);
});

I just tried downloading a file in Firefox using the Firefox underdrive extension and had no problem. I don't use Firefox for anything else, but it's worth having it for this extension alone. I have not tried it elsewhere because it's not worth the effort to install it elsewhere.

Been using the link (bookmarklet) in Chrome for a couple months and loving it. When I used it today at two libraries, clicking on the link and then the "Download MP# audiobook" gave me: "This lapl.overdrive.com page can’t be found No webpage was found for the web address: https://lapl.overdrive.com/media/download/audiobook-mp3/5217592 HTTP ERROR 404"

Same here. Just tried with NLB overdrive loans page.

Seems like it's over.

All requests to the odm endpoint return 404 Not Found.

This is not unexpected and I'm only surprised it lasted this long.

Does underdrive still work? Your links to the extension aren't working. Thanks.

Seems like nothing is working. All the scripts, addons and tricks I have tried do not work. Can anyone try to create a new working script or something? Thank you.

You must have tried before Friday. As of yesterday (Friday, 31 JAN 2025) the ODM files are now gone. It is still possible to grab all the "part" MP3 files but, after downloading them, one has to concatenate them into a single file (easy enough) and without the ODM file there is no way to get the metadata and chapter information.

What's your method of getting the MP3 files?

I thought Underdrive in Firefox was completely dead, but discovered that by clicking on the extension's settings and managing everything in sight, including permissions, I was able to activate a "Download MP3 files (experimental)" option. Unfortunately, after clicking "begin download", everything hung. No download has begun after more than ten minutes, so it seems that the experiment is a fail.

I've been using command lines since before DOS, but figuring out new things is harder than it used to be. I have installed a current Python distro for Windows 11, but have not yet braved the waters of ODMPY, so going through Libby is not an option. Libby downloads in the pure Google version of Android 14 are totally hidden, even with a file manager that shows hidden files. Where are my grand-nerds when I need them?! 😉

Has ODMPY worked for anyone in the last few days? I'd like to know that before I jump into that pond.

Haven't tried ODMPY since it needs an .odm file. I was going to use it this week when the bookmarklet failed.

I just tried the interactive Libby thing in ODMPY. I can authenticate and it sees my loans but when I try a download I get this:
An unexpected error has occurred

There's a bunch of error code under that. This seems relevant.

HTTPError: 403 Client Error: Forbidden for url: https://sentry.libbyapp.com

The information on the ODMPY page (https://github.com/ping/odmpy) says you can download audiobooks directly from Libby via ODMPY if you have Libby installed on a compatible device There is no forum option on that page, so I can't ask questions there, but the page does include dozens of command lines. Has anyone tried direct downloads?

Ah, nurho83 just answered that question. Alas! Obviously Overdrive is plugging all the holes.

Just use your browser's Developer Tools (press F12 on Windows, or Option + Command + I on macOS) and look at the Network panel. You will find that each part is downloaded in chunks of about an hour (plus or minus ~15 minutes) and you can just save those locally and then add the MP3 extension (if missing) and you end up with the same part files, without the user-friendly names. You can use any number of programs (like ffmpeg) to concatenate the files into a single one, if you prefer.

odmpy will only work when you feed it an ODM file. The interactive client does not work (even when using the forked version that had fixed that feature) because you can no longer get a registration number to activate a client associated with your account.

You actually can get the code if you follow this. It found my current checkouts and asked me which I'd like to download. That's when I got the errors I posted earlier.

It is. Until the odm files are able to be downloaded again (probably never) neither underdrive, nor the bookmarklet nor odmpy will work.
That's it. There's no magic here.

To anyone that wants to follow up, the easiest (in my opinion) way will be creating something that uses the listen in browser pages.

The chapter information is definitely there (in the html/dom) and if you intercept the mp3 requests you can save them to disk.

Good luck.

Hey you guys over overdrive, I guess you are watching us and laughing at us

Thank you , your extension worked perfectly until it was there

Go to Reddit and search for LJ_LongWing. The link is in the 3rd comment. Readme is pretty good. A couple of time savers: If you check out the book in Overdrive, you don't need to go to the Libbyapp. After hitting "Borrow" twice, you'll get the option to "Listen in Browser". That will give you what you need to do inspect/network. Second, if you don't want to do the command line and like me update all the meta data after anyway, then in windows file explorer you can just drag the har file you saved over the runDownloader.bat file. The files will all say "unknown" but will be numbered in the right order. Careful. Lets not let the Overdrive police take this away.

I'm using Audio Downloader Prime to individually download the parts of a book from the Listen in Browser feature. That extension "lights up" with a file count each time it detects a new audio file. I skip forward a few chapters to find new parts. Before I start a download, I streamline a file browser window to display only name, file size, and length, then use length to calibrate where to start looking for a new part. Downloading a whole book takes longer than a simple unified download took, but probably not longer than more complicated procedures with scripts and command lines. I clear the list after each download, then check the file size against the previous one to make sure I have a new file. No two are the same size. I add a part # to each new section and then slide them all into a new folder inside my Audiobook Stash folder before uploading the new folder to my Sansa player. With a little practice, I've gotten this down to around 1 minute per part. That extra time is a small price to pay for continued access and simple enough for this old granny to manage without calling in the grandkids! BTW, unfortunately this process does not work with the other streaming audiobook source (name begins with H) commonly used by libraries.

The method above takes about 3 minutes to do an entire book, which includes about 2 minutes to fast forward through a 12 hour book.

This has worked well for me, but I'm getting a Java memory error for longer books (I am not sure what the exact threshold is, but the book I have that is failing is 43 hours). Unfortunately since the download link only gives a .jar file, I'm not able to go in and view the original source code. I might piggyback off of the described method of obtaining a .har file and see if I can come up with a more robust solution though.

That would be great. Thought I'd run a test with Conroy's Beach Music but it's only 29 hours. :-)

This worked :)

Yes, a bit laborious but better than nothing

Are the Libby parts being broken into smaller and smaller pieces on new releases? Used to the chunks were about an hour(ish) but I just flipped through a less than 11 hour book and it downloaded 34 MP3s. Older releases seem to be unaffected.

I suspect those tiny parts are a fluke. I've recently downloaded several books with ADP and all seem to have the same hour(ish) part size. I've occasionally downloaded books via the previous app that had tiny pieces as well.

I described my technique in detail about eight posts up.

I don't think it's a "fluke." I just downloaded Robt B Parkers Buried Secrets both ways and got 60 files. Maybe Overdrive used to get all the books on CD's which would account for the 1h 7min files. Maybe now they're getting them other ways with the files chapterized.

Are you downloading recently published titles? I've recently downloaded titles that start sections with "Side Two", obviously ripped from audiotapes. A recent news release from Blackstone Audio announces that they'll be distributing audiobook CDs from Recorded Books. That format is still the standard.
