This is a great place to start, welcome to the forum!
A library will be absolutely required, and a good book to start with is this one:
The other thing that I would suggest, is look in the Nihonto info section at the top of this page here under the forum banner, there is a glossary there and I would suggest trying to learn the various terms used in relation to nihonto, at least try and learn as many as you can, they can easily be cross referenced with the above book. this will make the subject a bit more accessible and easier to understand, as there is a whole vocabulary of terms that are used when talking about Japanese blades. Perhaps try and learn a few different terms each day.
Have fun with this absolutely fascinating hobby!
