I've been contemplating putting a little one-liner up here the past couple of days, and decided, "what the heck?"... so here goes:
"Generally speaking: if a book is worth reading, it is worth reading again." By which I mean, I have long since come to the point where, if a book does nothing more than entertain me... then I consider it a loss; time wasted. Which is why, I suppose, I tend to avoid so much popular writing these days.
Mind you, there is absolutely nothing wrong with entertainment, or with books or stories (or movies, or plays, or...) whose sole aim is to entertain. But... all they are for, in the final analysis, is passing the time; preventing boredom. Reading them, one doesn't accomplish much else. One hasn't added a darned thing to one's understanding or appreciation of life, or the human condition, or the universe, or even how to craft a literary work of substance. Now, for those who are not looking to do these things... then entertainment is really what they are looking for, and by reading such books, they find it. Whether or not that book would entertain them on a rereading largely depends on the book, and on that particular reader's range in reading. (For example, those who have chiefly read modern, kinetically-oriented works will likely always have trouble with "leisurely, old-fashioned prose"... even though the latter often offers much more than the former.)
But, due to several experiences in my life, I've long had an extremely strong sense of my own mortality, and my interests are in tackling things which, in some way, enrich my life in the long run; whether that be in causing me to rethink attitudes about one thing or another, or aiding me to appreciate aspects of life or art I'd never considered before, or simply challenging me to think more clearly or expand my horizons a little more.
As a result of this, the bulk of material I read is something I will, if I can manage it, probably re-read at one point or another; some of it is stuff I return to again and again, gaining new levels of appreciation with each reading. On the other hand, books which were things I particularly enjoyed when younger and just looking for entertainment (though I wouldn't have expressed it that way then; I just liked reading!)... are likely things I will never crack open again, and have mostly gone to others who will enjoy them. A few exceptions exist, which I hold onto for sentimental reasons; but they are a relatively small percentage of what I own.
And yes, Chris: it does; and often of a very rich type....
