They're actually not that big. If you type the dots 1,2,3,4,5, and 6 altogether on the braille typewriter, when you read, your index finger can read the whole thing by itself.
Oh, and another thing: if you are talking about the whole book itself, if you imagine a text book, there would be massive amounts of pages! They have to type it out in volumes, rather than put the whole thing together. Can you imagine carrying the whole book around at schools all over the place? That would be impossible! Now, if you talk about a small book, let's say, like a children's book, it could still get up to 10 pages in braille! The reason for this is that braille takes up a lot more space than normal print. So, now you know somewhat of what braille is.
Blind people can't read books so they read braille books and signs.
You can find Terry Pratchett books in braille online through websites like the National Library Service for the Blind and Print Disabled or organizations like the Braille Institute.

There are many ways that books can be accessible for a person who is blind. One way (the most common way) is for a blind person to read braille books. There are many places that offer braille books. Some libraries provide them; many internet services provide braille books; etc. Another way blind people can read books is auditorially. You can get devices, such as an Apple product, that read books to you, once you get them in that format. Those formats are available in many places online.
