This is the only real solution (even if it's through an intermediate agent, which may have the same problem. Remember Google Reader). Of course, then the problem to keep that info in a good way (indexable, accessible, backed up, etc...) is another interesting problem.

There are tons of books that are out of print and cannot be easily found.
