TITLE: Open Source Abstract Algebra Textbooks
QUESTION [8 upvotes]: Does anyone know of any open source abstract algebra textbooks other than Judson's? I am about to write a small program for a friend that will generate a random algebra problem (for preparing for quals) and my idea is to go through judson (and hopefully some other open source algebra textbooks) and get the exercises, put them in a database and pick them randomly and then show it to them using MathJax or something. But I'm having trouble finding a list of open source abstract algebra textbooks that have the .tex files.
I would be content with finding online lists of abstract algebra problems with latex code that is easily parseable? 
Thanks!

REPLY [3 votes]: In the case of quals, there are normally old quals available (either from your department or other departments) and possibly old websites containing problem sets for graduate level algebra - it would be better to study those instead of random problems from an algebra book (especially a non-common graduate level book, since the likelihood of getting a useful problem for preparation is not high when selecting problems normally).
