Hello, I am trying to build some kind of database, preferably with an Index at the beginning, using Word documents that already exist.

First, I have around 40 documents that need to be merged into one documents. They are 2 to 3 pages each.
Second, I would love if their would be a an index at the beginning of my documents. Preferably in alphabetical order.
Third, I would love to be able to add new one that would add themselves in the proper order, both in the index and down the document.

Is that even doable in Word? If not, would you suggest some program? I do need to use the original documents though...

Thank you.
