This is true, for all but a minority of titles and editions imo. I have probably a couple of hundred hardcover and paperback and most of them nobody really wants. Collectively they are also quite heavy and difficult to transport from place to place. We haven't moved in a number of years but the last time we did my crates of books made up a significant portion of the total load weight. In the end I will probably sell a very few volumes that have a little value, give away a few more, and dispose of the rest.
