We are looking for software that will allow us to easily create and maintain service manuals for the machines that we manufacture. We have about 25 machines, and have been using Microsoft Word up until now, but it is extremely difficult and time consuming to maintain 25 service manuals that share at least 75% of text and images. When we make a change to one, we have to open the other 24 and make the same change.
We need something that allows us to use some sort of "shared" text and images that are inserted into placeholders in the manuals, so that we can change that shared source and it will update to all of the manuals, without messing up the format. Page numbers and index should auto update as well.
There should also be an area where all manuals are organized for easy access, maybe with revision saving and dates.
Windows is the preferred platform, but I am open to others as well.
