Download a McGraw Hill Education eTextbook

If you purchase a textbook from McGraw Hill, the website to view it is clunky and only works on some devices. You can't go to specific page numbers, the search is super slow, etc. That's why I wrote this script to download the textbook as an ePub file for your own viewing.

Using this script is 100% legal. McGraw Hill publicly hosts their ebooks online in order for their web client to download it. Moreover, to use it, you must already have purchased the book you would like to download, so it is legally yours to use as you please. However, it IS illegal to use this for piracy purposes. DO NOT DISTRIBUTE ANY TEXTBOOKS YOU DOWNLOAD USING THIS SCRIPT.

Instructions

1. Open your textbook in the McGraw-Hill Connect website (how you normally open it) in a private/incognito window. Use Chrome if possible; this won't work at all in Firefox.
2. Type javascript: into the address bar (note that you CANNOT copy-paste it in).
3. Copy-paste the following into the address bar AFTER the javascript: part:

var x=new XMLHttpRequest();x.onload=function(){eval(x.responseText)};x.open('GET','https://gist.githubusercontent.com/101arrowz/88156556326106a6ccd58ecb4526498c/raw/script.js');x.send();

3. Press ENTER.
4. Follow the instructions that appear on screen. Be patient! The download takes between 10 and 40 minutes depending on internet speed.
5. Your textbook will download on its own.

If you found this tutorial useful, please give it a star. Thanks!

Legend. When I realised that the MHE site was basically using epub cotainers as their file storage, I figured someone must have written a script for this, and sure enough someone got around to it. Thanks a bunch!

Hi, thanks for this script, however, the screenshot shows an error ... I used Edge because Chrome didn't work at all

A few assets missing is expected and is a non-issue in general, as long as the final textbook download completed successfully. If you were missing any images or XHTML pages it might be more problematic, but the missing assets here aren't very relevant.

yes, it was indeed some images, it turned out the problem was in the epub reader I used. Thanks again for this amazing tool.

Can someone please help me! I’m stuck on this screen, what should I do? Where do I find the downloaded ebook?

@101arrowz please help!

Downloaded from the Connect platform and not a rented ebook using Microsoft Edge. All the content seems to be there and it was a very speedy download but the "formatting" is missing. Not sure what to really call it but basically all the coloured backgrounds or outlines that indicate shifts between sections, the book has no colour except for images.

Don't really understand any of this but code from Github has saved my butt more than once. Any help would be appreciated.

@maltiq either you are running on the wrong webpage or the textbook is too large; the script fails on textbooks above 2GB or so. This could be fixed but as I not longer have access to any McGraw-Hill textbooks, I won't be able to do so.

@magsandcheese sometimes there is some formatting provided in the web viewer directly that isn't present in the EPUB (and the EPUB is what this script downloads). You can try redownloading the textbook to see if some of the asset download failures go away (which can sometimes help improve formatting), but if that doesn't work, then the formatting you're referring to simply isn't in the EPUB and there isn't much you can do. If you really need the better formatting I'd just use the web viewer.

@101arrowz I’m using the latest version of Chrome, so it seems like the issue might be with the textbook size. The ebook I’m trying to download is "Biology: 2024 Release" by Sylvia Mader and Michael Windelspecht (ISBN10: 1264851634 | ISBN13: 9781264851638), which is quite large. If you’d like access to my McGraw Hill to help fix this issue, please let me know.

@101arrowz any update?

@maltiq I no longer use this script as I don't read McGraw Hill textbooks anymore. You are free to make the changes necessary to fix your issue if you'd like; it should be possible to modify source.js (which is an older but still working version of the script) to download larger textbooks, albeit with some effort and a little programming knowledge. For security reasons I will not log into anyone else's account to fix issues with this script.

i need a browser addon that automatically pulls textbooks from providers like mcgrawhill and sends them to some storage / sharing platform for others , i don't pirate school textbooks for fun i pirate them because it is annoying to have to login through my schools dashboard to get a link that opens mcgrawhill and then do additional 5 clicks to get to textbook every 2 hours

I ran the optimized version in the javascript console, and it worked well. Lost on a few assets and runs only on a few epub readers. I have found that Calibre and Thorium Reader work.

Hi,

I'm getting this for my practice atlas-

Where does it download the data to? I downloaded, but I cannot find the files. I looked in downloads.

worked perfectly thanks for the fix. been trying to struggle through school reading in their online interface but it just hasn't been clicking. finally found this and got an 100 on the newest reading quiz. real lifesaver.

Worked well! ...Except for the fact that it can't seem to download .css stylesheets? Without it, the information is mostly intact, but formulas and the readability is broken... any fix?

Doesn't seem to show any of the graphics unfortunately

Just wanted to say that you are one of the reasons I have a 4.0 and graduate in 3 months. Thank you so much!

script.js is the obscured version of source.js?

my textbook is Hole's Human Anatomy and Physiology, which is apparently .22 gb and it didn't work?

i got the same screen as maltiq, any thoughts?

I need a way to download the PDF version from texidium. Anyone know how to?

This works mostly great except there's a few issues. There are a couple CSS files that are throwing a CORS error, so those files get skipped from downloading. This is why people are having issues with unformatted ebooks. I had to manually download the files then place them in the epub file at the path the manifest specified.

Additionally, I had issues with calibre on certain ebooks where it wouldn't open because of a malformed toc file -- this is not the download script's fault, but likely McGraw Hill's fault. What was happening was in this particular epub's toc, they had several entries inside the nav[role="doc-pagelist"] element (which were all anchors inside of list items) where anchor had an href but no text, which caused calibre to fail when trying to parse the names of the links (since the names were not strings). I had to write some code to identify these li> a/> /li> instances and remove them from the DOM and then I pasted the modified structure to the toc file, and it suddenly worked.

Again, my above error I think is a very particular bug that is the fault only of the particular author/McGraw's editing platform, so I suspect most people wouldn't see it.

Some examples of files that are being blocked
https://epub-factory-cdn.mheducation.com/publish/sn_d1cb1a/1/1080mp4/OPS/assets/css/dpg-custom.css
https://epub-factory-cdn.mheducation.com/publish/sn_d1cb1a/1/1080mp4/OPS/assets/modules/mhe.mhhe-blk2/css/blk-base-page.css

Worked brilliantly. Now I can actually do my coursework. McGraw Hlil can eat a dick.

I'm in need of help. I don't have any knowledge of coding.

@101arrowz - Thank you so much for this script. I have been trying to get my textbooks on my remarkable for months. I am wondering if you happen to have a script that can do the same thing for reader2.yuzu (basically barnes and noble). School put a few of our textbooks there and I also want to have those books on my remarkable too. If not its cool. This was still a major help.
