For printsets, 600dpi may not be overkill - it is probably about right; 
some of that linework and small text really is spidery. If in doubt, 
scan a page and ask for opinions, though a good rule of thumb is: "When 
viewed pixel to pixel, is all the text and linework completely clear and 
unambiguous or is it breaking up, and hard to decide if that is a B or 
an 8".
