Peter Brantley -- At
The Millions, Max Magee suggests that the trend in book size is toward the ... physically infinitesimal:
"I've written in the past that books are too big -- not too long, but too bulky and heavy and expensive -- and pined for a return of the pocket paperback, so that carrying a book with you didn't feel like such a chore. A combination of factors led to the demise of the pocket paperbacks that were prevalent in the middle part of the 20th century. These pocket paperbacks had been sold at newsstands and drugstores rather than bookstores, but as these venues stopped selling books, the pocket paperback market shrunk. Around the same time, a wave of consolidation hit the alternative book distribution network that had sprung up around these pocket editions, shrinking the number of books available, and consolidation among publishers folded the purveyors of the pocket editions into larger publishing conglomerates built on a different business model. Finally, the introduction of the trade paperback -- the larger paperbacks prevalent today -- squeezed the pocket edition out of the publishing equation except in a few genres -- romances and mysteries -- that still cling to the similarly-sized mass market format (which you can still see at grocery stores and in airports).

"A full-fledged return of pocket paperbacks would be surprising, however, as ultimately it seems likely that an even smaller format will take center stage, a format that is indeed infinitesimal. With hardware innovations driven by
Amazon's Kindle and perhaps Apple and Sony as well, reading on these devices will become more palatable for a larger percentage of readers. Selection of titles will improve and developments like Google's recent deal with publishers will
further expand the availability of titles in digital formats."
