In terms of what I was discussing before regarding math texts, where an instructor might choose different sets of material to go through, and where we might have to write things differently depending on what has gone before: We can put all of the math material in one big database, while different math texts are offered (or constructed by new users) that go through different modules in different orders, according to the needs of different courses. No need for �If you know concept A, read definition X, but if you know concept B, then read definition Y.�, since the reader can just click "Next" in any well designed textbook to get to whatever definition they're supposed to use. Now making the /index/ develop automatically and correctly -- that may be tricky, but it should be possible. -- Toby

For my proposed application, with different orders for the same material being counted as different "books" to allow teachers to choose the order, this would be rather difficult to keep track of, with a link like "Next page in Calculus using course sequence #14". Or was this class using course sequence #4? -- I forget. ^_^ -- Toby
