Would anyone here by chance know where to find a Gradus ad Parnassus on the internet? For those not in the know, a Gradus ad Parnassus is a book useful for putting together Latin verse - detailing long/short syllables and alternative words etc. Google is less than fruitful today, and the one I have so far come across is less useful than one might expect.

I ask for a lot, but if any of you have heard of such a work and know where it may be found that would be super.
