All things being equal (money, space, etc), would you rather own copies of the books you read? Or borrow them?My personal preference is to own the books. Once I've read a book, the odds seem to be that I'll re-read it if I really like it. Most of Mercedes Lackey's books, for example are books I've read at least five times apiece (and for some of those, I borrowed them that many times from the library).
These days, I've taken to borrowing with an eye to later buying (perhaps when the book comes out in paperback, or when I can afford the book). And, only one book at a time. When I borrow more from the library, none of the books get read at all. When it's just the one book, it's likely to get read right away. Some of the most recent examples of books I've borrowed include: Lover Unleashed and Kings of the North.
The problem with liking to own the books I read is my habit of thinking "this looks good", or "that'll be useful one day (with history books)", but then I keep reading the new releases rather than the books on my unread books list (a scary 170+ books list). So, what's the solution?
My guess is, it's to just keep on buying books.
