Thanks everyone! This is great discussion and food for thought. I would eventually like to move this organization to an e-manual format and would envision a slick hyperlink type format so people could toggle back and forth between the document and a definitions page.
In regards to having definitions in each of the documents where it is referenced. That would make the most sense but what I found at my last employer was that the definitions would not be consistent from document to document as time and updates rolled on. That was my motivation to think about a one-stop shop for definitions.

ETA: I meant to say that the consistency lacks from document to document when a definition is used in multiple documents.
