I would not have guessed the number of people who are both iPhone users and O’Reilly book readers was large enough to support such a massive library. But I find myself having a similar experience in the App Store as I used to have in Borders and Barnes & Noble in the computer section. For any super-dweebs with a similar insatiable thirst for deep, deep tech knowledge, search on O’Reilly and Show 25 more, and Show 25 more, and Show 25 more, and Show 25 more, and Show 25 more. You can assemble quite a library (which appears to update just like apps) for 1/4 the cost of quickly out-of-date dead-tree versions.
