11 years ago I didn't see "Schaum's Outline of Calculus of Finite Differences and Difference Equations" in the list above, so perhaps the current offerings on their website don't match the full back catalog.

11 years ago As it so happens, that volume is one which I am quite familiar with as I studied it in the eighth grade when I was teaching myself calculus. I picked it up at a local used bookstore, where I also found other math books. I would be quite happy if PM could wind up serving a similar role to that bookstore for eighth graders who are interested in learning math.
As a rough measure of feature parity, let us consider each section as equivalent to an encyclopaedia entry. That particular value has 97 sections and 877 problems, 420 of which come with full solutions.
Assuming all the books are of roughly the same size, that comes out to something like 6000 encyclopaedia entries and 60000 problems with 20000 solutions. The number of entries is something like half the number we currently have; however, I think we would have to add a few thousand entries to be really comparable, since our coverage in most areas is spotty.
The quickest way to achieve this goal would be by the books project since we can enter old textbooks which cover the same material and have problems. In order to get the solutions to the problems there in a reasonable time, we will need to get to the point where we have 60 solutions per day coming in.

(* 420 65) ;=> 27300If we could recycle the encyclopedia, we'd be OK! -- we'd want to add about 5 problems per (current) encyclopedia article. That sounds like a lot of work, but an interesting project nonetheless.
This might go someplace on the Books project roadmap, see #37.
The outline of outlines is as follows:
