I read a book called baby led breastfeeding that I got in the library before I had DS. I can't remember the specifics but I felt it was really helpful at the time especially re. What to expect/how to handle first few days/weeks. Some bits would be good for a partner to read too so that they have realistic expectations.
La Leche League breastfeeding book with a red headed woman on front - really helpful prereading!
Anything by Dr Sears - he's into attachment parenting/breastfeeding, etc. and I spent many a day/night being comforted in what I was doing as he seemed to agree with it. He has books in sleep and fussy babies.
What to Expect is fab for pregnancy and beyond.
Life After Birth - realistic expectations for the modern woman.
Get reading - knowledge is power! I stopped after DD got to 6 months but I found all the books helpful in the beginning.
I read lots on here actually for breastfeeding first time & it really helped.
I searched breastfeeding & loads of threads came up with lots of advice. Also La Leche & Kelly Mom websites are helpful.
I did learn that it can take 8 weeks to get the hang of, top ups can affect your supply so skin to skin as much as possible. Drink loads, I drink at least 3 litres a day & poking out tongue & hand sucking means milk is needed. Baby's shouldn't be crying before feeding.
There was none of that in the literature I was given/came across.
