In an ideal world, every book could be given an "importance" score, for some arbitrary value of importance. For example, how often it is cited. This could be customised on a per-user basis, depending on which subjects and time periods you're interested in.
Then you can specify your disk size, and solve the knapsack problem to figure the optimal subset of files that you should store.
Edit: Curious to see this being downvoted. Is it really that bad of an idea? Or just off-topic?
