I am a college professor working on an author´s library catalog. I have two Word files each containing one version of such a catalog. One file is 604 pages, the other 281. The goal is to merge both files into one master catalog that would eliminate duplicates. Before merger, however, both files require editing, mostly eliminating extraneous matter that would hinder merging. I therefore need someone very familiar with MS Word or another program that would facilitate editing and merging and, eventually, reconversion onto MS Word. I am attaching one catalog herewith. The extraneous material in question are numbers and al marginalia.
