Or the most legal way (yet) to do so if you don’t have access to a Windows computer.
I have recently obtained from the (public) library of my (public) University a copy of the book “Apache Maven 2 Effective Implementation: Build and Manage Applications with Maven, Continuum, and Archiva” by Maria Odea Ching and Brett Porter. Alas, the download comes as an Adobe Digital Editions file locked with DRM and it took me some effort to be able to read it on my Linux machine (Ubuntu 14.10 Utopic Unicorn), I will outline here the steps I had to take.
There are several guides (1,2) (also in Italian, (3)) on the internet about installing Adobe Digital Editions but they tend to get out of date pretty quickly. The advice on Adobe forums is also sparse (1,2). Most of the guides suggest to use Wine but the newest releases of Adobe Digital Editions (v. 4) require you to download Microsoft’s .NET Platform which is, from my experience, a blocking step. I have tried to use the latest versions of Wine, and other derived softwares as PlayOnLinux or Crossover and I wasn’t able to get Adobe Digital Editions 4.0.2 to even finish the setup.
In the end, I found this solution (more aq patch than a solution, actually) that makes use of a Windows virtual machine that you can get legally.
This procedure will require you to download and install a ton of proprietary software and accept their licenses and terms. Alas, there seem to be no alternative or workaround to that at the moment. I think this is a classic example of the number of reasons of why DRMs are defective by design.
A general disclaimer: the advice you will find here is intended to show what you have to do to read book that you have legally purchased or acquired to these software. The point of this blog post is also to show how much trouble Linux users have to go through to do so, in the hope that this will demonstrate that DRMs are not a solution to the problem of managing how copies of digital works are done. I didn’t review (nor I have the intention to review) all the legal terms attached to these software, but you should review them if you are concerned. Still, this is probably better then downloading software from unknown sources but it’s probably out of the boundaries of what you can do as per the various licenses. Probably you are not allowed to take all the steps below just because you will be “circumventing” DRM. Probably «You’ll be a criminal either way». Use this guide at your own risk. You have been warned.
If you think all of this DRM stuff is nonsense and if your library distributes DRM-protected books, please join the FSF in calling on libraries to eliminate DRM, also consider the possibility of writing them a letter.

Finally¸ you will have in your Calibre library a file that you can read on any machine (and any device,in fact you can use Calibre to convert your book in the format you need).
This guide is already quite long, so I avoided dwelling in details. If there is something unclear please ask in the comments and I will try to answer you and update the post.
