Finding Darboux Sums Online: Any Suggestions?

[sutupidmath]

HI guys, i was wondering whether there is any site online where i could read about darbu sums. Because i want then to define the definite integral using darbu sums. I had a book, written by a russian mathematician, but i forgott it home, so there is no way i can get hold of it.

So, any suggestion?

thnx

Spelling "Darboux" correctly will probably enhance your Google searches.
