There are two ways:
either enquire with / join the specific breed clubs
or buy the "big boys book" 5th edition ( currently on 6th) for about £30 or less
the breed clubs are rightly fairly conservative and whilst there may be slight changes they wont be vast.
I would suspect you will get into other breeds so the big boys book is the way forward and then if you have found it usefull and have more breeds then the 6th edition for a birthday / xmas present further down the line
