In response to this blog entry, Dorothy from Australia asks the following:

Kia ora 

I am hoping you might be able to help us. We are using an Ubuntu OS on our ASUS eeePC netbooks at our school in Auckland, New Zealand. We really need an eBook reader for our netbooks – especially one that handles DRM for books loaned from our school library system.
Do you have any suggestions of software we should try? I wasn’t sure whether to contact you via your blog or the GCT forum, so apologise if there was a better way to ask. I did think that if anyone would have a good suggestion it would be you 🙂

I’m guessing Dorothy is asking about what to do with Overdrive books available via libraries, which was in a bit of controversy back in March, 2011. Overdrive uses Adobe Digital Editions as their primary tool to handle DRM’d ePub books:

Adobe® Digital Editions is a free application used to read EPUB eBooks. Additionally, Adobe Digital Editions support eBooks in the PDF format, but results have been known to vary occasionally based on a number of factors including the complexity of the book (novels tend to render beautifully while complex text books with graphs and charts may render oddly) and the quality of construction of the actual PDF file. (Source: Overdrive)

As you might guess, as a result of the focus on DRM, there’s NO client available that I know of for Linux that reads digital restrictions management (DRM, ok ok, it’s officially “digital rights management”) ePub ebooks. So what to do?
I started writing the response in a comment–offering two solutions–and then realized I was going quite long! So, here’s the extended response:
Dorothy, unfortunately, I don’t know of any program on Linux that will read a DRM’d ePub book. 
The only way would be for you to remove the DRM (don’t do it!), then use FBReader for Linux (sudo apt-get install fbreader) or Sigil ebook viewer to read the ePub book. Obviously, this is an illegal proposition that could land you somewhere undesirable. Before moving on though, this might be a teachable moment depending on the age of your students on DRM and the problems, a perspective encapsulated in this series of comments:

DRM is used by publishers to restrict what you can do with your ebooks. DRM controls which devices you can use to read your ebook, and stops you converting your ebooks from one format to another. DRM makes buying and using ebooks harder. When you first start using ebooks, you might not notice the restrictions very much. But the restrictions are there. 

There are several different DRM schemes. Ebooks with one DRM scheme can’t be read on a device that uses a different DRM scheme. Some DRM schemes limit ebooks to one device only, so if you want to read that ebook on a different device, it’s necessary to download the ebook again. Others require new devices to be authorised by a central server on the Internet. 

When you want to use a different ebook reader, or if the supplier stops supporting the ebooks you’ve bought, you may lose access to your DRMed ebooks.
So to be able to read your ebooks on all the devices you have now, and to be sure that you will still be able to read your ebooks in the future, you will want to remove the DRM.

As you can see, removing DRM from ePubs gotten from a library would raise more ethical and legal questions than you would want to deal with in the context of getting ebooks onto your students’ Ubuntu netbooks! In other words, it would be more trouble than it’s worth!!
I do remind you that there are many free book sources online (which can easily be read with the aforementioned FBReader), and the tools for creating non-DRM’d ePubs is increasing, enabling your students to create content for each other. You can even use LibreOffice on your Ubuntu netbook to create ePubs! (another resource)
Still, in case you do want to pursue accessing DRM’d ePub books via Overdrive, here are two possible options you can try:
1) Run Adobe Digital Editions via WINE on your Ubuntu netbook. This will allow you to authorize 5 computers, as I recall.

a) Download it here –
b) sudo apt-get install wine on your Ubuntu netbooks
c) open the Adobe setup.exe file with WINE. At the command line, this would look like this:
wine setup.exe
d) Here’s what the installation will look like:

Notice that everything seems to be working quite well on the install…this is Adobe Digital Editions running on Lubuntu 11.10.  I just went through this process as I was installing it, and it went quite smoothly. Unfortunately, I haven’t purchased a book through Adobe Digital Editions (ok, I’m only buying DRM’d Nook ebooks) but I expect it will work…here are some resources that show it works:
Source: In Spanish- Adobe Digital Editions via Windows in Virtualbox environment
2) Use to setup a Windows virtual environment.

a) Install Virtualbox on each of your Ubuntu netbooks. You can get the appropriate installer here:
b) Setup a Windows virtual box–where you install Windows.
c) Install and authorize Adobe Digital Editions for Windows in the virtual box you just created.
d) Copy the Virtualbox files to an external USB drive then put it on multiple netbooks. This assumes you have multiple Windows licenses (to stay legal). I’m not sure how this would affect the authorized Adobe Digital Editions (whether Adobe would “catch on” that it had been duplicated across multiple machines or not).

I hope this is helpful to you, Dorothy. Approach #1 seems the best for your scenario given what little I know of Overdrive, Adobe Digital Editions!
