Okay so a few helpful bits for people.
The books on the Osprey Site can be found Here.
I have to admit I bought mine through Amazons Kindle store as its easier to carry them all about and a few pennies cheaper.
You can also find all the Reference sheets you need on the Osprey site Here.
Things like the QRF and Spell sheets are amazingly handy for every game you play.
