I have an extensive hard copy library that cannot be revoked, revised, disappeared or otherwise fvcked with, as repressive regimes tend to do. They’d gave to go all Fahrenheit 451 on me. The survivors would, anyway.
Like ours. I have a fairly extensive library of both real books and Kindle, and the latter really excited me with the idea of a whole library in my pocket. Until the 1984 scandal. There one day, gone the next. Amazon says they'll never do it again. Sure they won't.
These can be backed up, however. There are several free Kindle format converters that will take that AMZ format to a PDF and free you from the greasy Amazon fingers riffling over your collection.
I've gotten into the habit, though, of purchasing a dead tree edition of anything I think is good enough to justify the shelf space. Because you never know. The idea of politically correct teams of "firemen" burning your library was perfectly silly when Bradbury wrote Fahrenheit 451, but it's very believable now. Maybe I'll bury mine for a future and more deserving generation...
