Adobe's simple, solid, unglamorous Digital Editions software is your gateway to HotSpot Confidential if you're packing a Sony Reader Digital Book.

It's also a solid choice for the digital deviceless. Adobe has versions for both the Mac and Windows.

Once it's up and running on your digital axe, you may notice that Digital Editions feels oddly uncomplicated, like maybe it's a cog in a much bigger machine. That's because it is. (And that's why it deserves a gerund like "leveraging" in the title of this nugget.)

Digital Editions is just one piece of an Adobe e-publishing ecosystem that includes Adobe Content Server, an industrial strength product aimed at major publishers with a lot of commercial content.

That's "commercial content" as in stuff that publishers are not inclined to give away. So if you bang around the publishing industry side of the Adobe site, you'll detect a strong emphasis on digital rights management (DRM).

Adobe has been working on copyright protection for years, centered around formats like PDF. So they are pressing that advantage with products aimed at publishers with some assets to protect.

But that's outside our simple content transaction, no? So just download this free apple off the Adobe tree and put it to use in your own content acquisition strategy. You can even jumpstart your digital library, after adding HotSpot Confidential of course, by downloading free chapters from Sample eBook Library.

BTW, if you're interested in keeping up with Adobe's evolving plans, check out the blog maintained by Bill McCoy who is General Manager of Adobe's ePublishing Business division.

McCoy does a good job tracking e-book developments from an Adobe perspective, and he is one of the most outspoken and articulate proponents of e-book DRM.

Check out, for example, this November, 2008 post on O'Reilly's TOC blog.

McCoy is also an enthusiastic chronicler of EPUB-related developments. Adobe began backing EPUB a few years ago, after trying unsuccessfully to establish PDF as an e-book format. To their credit, Adobe execs realized that EPUB was better suited to e-books, which have to "reflow" to display on a wide variety of digital devices. Once they gave up on PDF, Adobe embraced EPUB with a big corporate bear hug, making it one a major player on its digital publishing team.

Significantly, InDesign, one of Adobe's flagship publishing products, now trumpets its "export to EPUB".
