I have some stuff lieing about for my day job that can probably help with this.
If you have electronic versions of the texts, I can first scan them for any non-dictionary words, and generate small snippets showing the context in which those words are used.
Slightly harder, but still doable, is to look for apparent proper nouns on the basis of capitalization; I expect to get some false positives that will need weeding out.
Alternatively, if you have a friendly software helper, put me in touch with them, and I can discuss tools and methods with them. The actual tool that I would use is proprietary, but there are good free alternatives.
