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!

Tried in edge too. Did not work for me. Nothing happens in the network tab too. :(

I'm not a pro, but I figured out that we need to override the current address bar from the textbook page with "javascript:......", it worked!! Just wanna share this with people who are not familiar with how Java works :)

Worked perfectly, I actually ran it on safari. Was my first time running a javascript on a webpage actually, I've only recently been getting into code and AI related stuff so it felt very nice having it work on my first try :3 Thanks for providing this, it's gonna help me a ton at school

Run the optimized version to have better luck

The instructions should do exactly the same thing as script.js - actually, the only thing the instructions do is run it - but yes, you can also paste script.js into the developer console to run the program.

Hey, I keep getting this issue repeatedly when attempting to download my textbook. I bought lifetime access to it through McGraw-Hill. I've tried running the script on multiple browsers and it either gives this error or another one stating that it can't create a "blob". I have 32GB of RAM and all of my storage drives have TB worth of space. Any help is appreciated cuz I'm desperate to get this textbook. Thanks in advance

If your book is over 2GB in total size the script may fail; I may not be able to fix that anymore as I no longer have access to any McGraw-Hill ebooks, but I'll check if it's possible to do anyway.

Worked on Edge, thank you!

Thank you so much for providing this! I was able to successfully download a textbook from mcgraw hill. But I was wondering does anyone know if there's something similar to the macmillan textbook. i have access to both achieve.macmillan and macmillan.vitalsource. Please let me know if you need more information to help me with this. Thank you in advance :)

Worked like a charm, thank you!

OMG it worked! Awesome! Is there one for Wileyplus?

Wow! Thank God! Worked the first time itself and like a charm! Unlike so many useless Python scripts that are out there for almost about everything! Thank you so, so, so much! :)

Frankly, I don't find McGraw Hill Education's e-textbooks particularly interesting. They may contain useful information, but they are usually presented in a rather boring format. Although it’s hard for me to judge, I like regular books more and get so carried away when I read that I use assignment writing services for university, I found https://ca.edubirdie.com/assignment-writing-services for this. In general, I prefer to learn through more interactive and engaging methods, such as educational videos. So for me, the electronic option is not a priority.
