I think it hinges on the paper and print quality mostly. The binding can be repaired if one treats a book a bit rough (my library offers a workshop for that...). While I have heard that the usual paper quality used for printing has degraded, I haven't seen any indications of problems in my own books so far. I also regularly consult books in libraries whose printing dates range all over the 20th century. Of course, they may not be pretty any more, and the paper often becomes yellowish, but treated somewhat decently they seem to age well and still be completely usable.
CD's and DVD's are another matter unfortuntaly... I am now basically operating under the assumption that any CD or DVD will be unreadable after a few years.
If I'm not mistaken then libraries buy a higher grade of books designed to endure much more. I've seen it on Amazon. i.e. a book comes in ebook, paperback, hardback & then another category - the name of it currently eludes me though.
"Library Binding" may be the term you are looking for - though this is not necessarily available from the publisher and libraries get it done after purchasing a regular copy. Some publishers offer Library Binding editions of some of their books.
