First time breeder needs help!

I've been asked to recommend a good book to help guide a first time breeder through the process of mating, birth and rearing the litter.
Before you ask, they're booked in for the relevant health tests for Miniature Schnauzers and they have some people who want the pups. Owner is also prepared and able to keep any pups should there not be enough suitable homes.
So if you want to be well bred how can you be well read?
Is there an really practical UK book on breeding?
Any other tips? I've not bred a litter for decades. When we did we used a pig lamp and my dad made a wooden whelping box with pig rails. What do other people use who don't have a master carpenter in the family!
We were also very hands on during the birth. Cutting chords etc and moving pups into a separate box with a covered hot water bottle as we had massive litters and there was always another pup on the way. What's the current school of thought - who lets their bitches DIY? And I seem to remember the vet used to come to give an injection to make sure there wasn't another pup or a placenta stuck - but I guess these days everyone can have scans so knows how many pups to expect?
Any other advances in breeding you can pass on?
