See this hardcover copy of Michael Crichton & Richard Preston's Micro?
It was donated to our little school library by a Science teacher (figures, right?), but was missing the dust jacket. Just a plain black cover. So I found the cover image online and pasted it into a Word document so I could size it correctly for printing. Then I opened up another Word doc and copied and pasted the book description from Amazon, plus a crop of an image from another edition of the same book (I think the paperback) so there'd be some sort of graphic on the back.
After I printed both pages out and trimmed them to fit the covers, I glued them down, then covered them with clear contact paper, which overlaps onto the inside endpages, so hopefully it's all very secure and will survive intact.

Also, we have no book budget at all, and depend completely on donation programs and the generosity of parent groups. I take what I can get!
