There are a number of mathematical books/monographs that do not have indices. In some cases, this is no huge deal; for instance, it is often easy to find something in Bourbaki using the table of contents. However, sometimes it can be incredibly frustrating. For instance, in Mumford's Red Book, if you want to know what it means for a prescheme to be a scheme (in more recent terminology, what it means for a scheme to be separated), you have to look in the section titled "The functor of points of a prescheme." Pedagogically, it works, but who would ever think to look there?

Thus, my "question" has two parts:

1) Are there any good resources (online or otherwise) that provide indices for such works as the Red Book?

2) Assuming the answer to 1) is no, could we, as an online community, produce such a resource in the answers to this question (which I am making a community wiki for this purpose)?

To try to jumpstart 2), in case the answer to 1) is no, I am including as an answer a partial index I have produced for the Red Book. This is also to show I am not asking others to contribute to something that I myself have not put time into.
