Information Regarding PDF e-Books

In Brooks Jensen's recent Lenswork podcast, which one can listen to here, he extols the virtues of using pdf format e-books to enable photographers to reach a wider audience, while avoiding the fiscal constraints that are associated with publishing a physical book. I was intrigued by this, though I wonder if the constraints are as strong as implied given the newer methods of self-publishing associated with print-on-demand services available from companies like Blurb.

Nonetheless, I found the idea interesting and tried to search around the internet a bit for information about designing and producing a pdf photography book. However, I found very little out there. Now, I know very little about using Adobe Acrobat and suspect that my inability to locate information on this subject may simply be that what is required is a good general book about how to use Acrobat, as opposed to special information on how to create pdf photography books.

So, I guess I am hoping that perhaps someone out there might be able to provide some good resource books or websites on the topic of how to use Acrobat to publish photographic e-books....or at least some place to start obtaining a bit of background knowledge. Anybody want to make suggestions????
