I am working with hugh spreadsheets ( 80+/- columns by 3000+/- rows),
I have to take other workers spreadsheets and make a master copy.
The other folks do not track their additions, deletions or updates to their
spreadsheets. Hugh problem.

I need a book or reference to tell me how to run or create formula's to do
this.
Any recommendations?
