Should I Throw Out Books?

I do not like to throw things out and my house has a full basement, so from time to time I pack things for which I have no use, now or in the foreseeable future, into plastic boxes, label them, and lug them down to the basement. That includes old magazines, obsolete computer gear, and books. Two boxes worth just this evening.

The implicit theory is that some day, twenty, fifty, or a hundred years from now, a future occupant, perhaps a descendant, will find what I have stored of interest. In some cases the idea is not entirely implausible. The LNW80, for instance, that was my first computer, might be fun to play with for a future kid with an interest in gadgets and the history of technology, and similarly for my vectrex game machine. 

But what about books? My younger son reads them as kindles on his phone. There are lots of people around, of course, who still prefer to read books as books, one reason I have just been converting two of mine, currently available in the form of Kindles, into print on demand hardcopies. But will there be lots of such people fifty years from now? I doubt it. And if there are, there will also be a lot of old books for them that nobody else wants.

Which makes me think that instead of putting books I will never read in the basement, perhaps I should put them in the trash. But I don't have the heart to do it.
