Believe me, you don't need a book to do this. (Assuming you know how to
develop photographic prints, that is, which is explained in any basic
photo book.)
All you have to do is find stuff you think might be interesting, put it
on top of a piece of photo paper in the darkroom, expose the paper to
light, and develop it. You can learn all you need to know through
experimentation (different objects, different length of exposure,
multiple exposures, etc.) Try it--it's fun.

I hope that in a few years it [Wikipedia] will be so bloated that it
will simply disintegrate, because I can't stand the thought that this
thing might someday actually be used as a serious reference source.
Because in its current form, it's not to be taken seriously at all.
