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!

@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.
