Gil Student wrote an article in Jewish Action, the OU magazine, on the changes in Jewish and mainstream publishing. He avoided the one big question looming on the horizon of Jewish publishing, as it is beginning to make inroads into mainstream publishing: the e-book.
He addresses the information-chunking and short-attention-span issues pretty well.
But there need to be heterim found for e-book readers on Shabbos, if we're not to have people dropped from Orthodoxy for "half-shabbos", esp. as more and more seforim are online in PDF and etext, if they wish to learn Torah stored in an ebook reader. Do you really learn all those seforim in your shrank, bought when a kid in yeshiva, or are they mostly for show, and occasional reference?
I carry around a good-sized library in my e-book reader, whether Torah or fiction, academic or popular material. Until people start using iPads or Kindle DX's widely, things like Gemara pages will still be difficult, although who knows - maybe the small-format Gemara may yet make a comeback. I have, for instance, a scanned PDF of Bava Kamma from the Lemberg half-page edition on the ebook-reader. Legible, but barely, on the 3x4" screen. But if I can get e-texts of Rishonim from Bar-Ilan, in pieces (how many blatt gemara does an in-depth once-a-week shiur cover, after all), that makes it more accessible to be on the Palm or the EZ-Reader.
The standard Gemara page was defined by Bomberg in the 1520s, because he issued the first full set of Shas. It made sense to keep using the same pagination for standard reference. Why did he use that page size (folio pages)? Ultimately, because of the size of sheep. Sheep are a certain size, so their skins are a certain size, which governs the dimensions of parchment pages made from those skins.
Technology has changed. We need no longer be governed by the sizes of medieval sheep. It is certainly possible to maintain indicators to standard pagination in text of other configurations (just look at, e.g., a two-volume two-column Zohar of the 17th century which has indicators of the pagination of the by-then standard three-volume single-column Zohar, so you can find page references easily.
So too here - as e-readers and pad computers improve, we should be able to use them with cross-linked etexts of the Talmud, Tanach, Midrashim Rishonim and Acharonim. Must we continue to spend hundreds of dollars on dead trees for use on Shabbos alone? Perhaps rabbis should work with electrical engineers to design an e-book reader that will not violate Shabbos, as Tzomet has done for doctors and the handicapped. Perhaps we should resurrect the arguments used by RSZA, and only not implemented out of respect for the Chazon Ish, and find ways to use solid-state technology lehagdil Torah uleha'adirah. After all, we don't slavishly follow the Chazon Ish, at least not in Galut, where we don't eat normal gelatin (which the CI approved).
If we don't find ways to adapt to such changing technology, then we, and our dead-tree obsession, will be left in the dustbin of history, along with our decaying paper.
