Firstly go to your local library, and check out what they have got. They will almost certainly have the John Seymor book, that although more of a coffee table book gives a good introduction to smallholding. (New edition 2001)
However on gardening there is a lot of rubbish been published recently, most of it along the lines .... as seen on TV.... My gardening books that I refer too regularly are:
Monty Don: The complete gardener (also a bit of a coffee table book, but very informative)
Michael Littlewood: The organic gardeners handbook
Pauline Pears: Bed system (for spacing, as I have raised beds in my garden)
For diseases etc:RHS Encycopedia is good, there is also an Organic one, but haven't got it.
All these books are in the libraries I'm sure.
On goats: Ulrich Jaudas: The new goat handbook (only available through abebooks, as out of print)
and Storey's guide to raising diary goats by Jerry Belanger. Although its American, it had lots of info for homemade remedies etc in it. For goats the British Goat society (BGS) has a very good website.
Again there is lots about beekeping in the library system, but I would think trying to get on a beekeeping course (try to find your local beekeepers asociation, they quite often run courses, and/or are quite happy to let you tag along to meetings at the hives in summer) before you read loads about beekeeping. I read the books and found them quite difficult to follow, once I did it myself it all became clear....
Happy reading - but honestly, just lpoughing through the forum will give you lots of ideas/knowledge for everything related to smallholding!

Oh and all of the HFW books on cooking - with the River cottage cookbook also having got a lot of smallholding info in. But probably not if you are vegetarian....
