Thank you, that's a good point. The site started off with just the BBC Micro version, and I never expanded the book references to be clearer.

Anyway, I have reworded every reference to books in the commentary so they now contain the full title and author list, so hopefully people will be able to find the relevant tomes. I've also linked to the books from my "useful links" page in a more prominent manner:

I hope that helps!
