The issue is 34 pages long.
The issue contains one essay:
Words: The Ebook Marketplace, Part 2 pp. 1-34
More on the last few years in the ebook marketplace, this time focusing on ebook pricing, ebook and ereader sales, software, the past and future, (intentional) humor, rights--not so much DRM as ebook readers' rights, and a few miscellaneous pieces.
If you're waiting for "ebooks and pbooks" (note and, not versus)...that's coming in January 2014.
This completes Volume 13.
The indices will only be available as part of the print version of Volume 13, which will be announced when it's ready, probably some time within the next couple of weeks.
