When I create a map book, using data driven pages, when I place teh actual pages side by side there is some overlap, so the pages do not line up exactly. Is there a way to clip the overlap so that the pages are fairly seamless in the map book?
Yes, the overlap can be adjusted in the DDP toolbox. In the second tab "Extent" there is the option to set the map extent. If you change this value to 100% there should be no overlap between your pages assuming the layer you are using lines up correctly.
