Hi there.
If it doesn't have to be a book, and you're just looking for general PCB layout design for a beginner, some of the pdfs in the rar file below, and maybe a couple of the links in the notepad in there, may be of use.
Application notes for PCB layout/design are usually good and always contain something worth spending the time reading.
If you find other interesting documents about layout that don't require an engineering degree in maths to implement, please let me know, thanks. Block component/functional groups, decoupling, ground paths*, things like that...
are you planning PCB design as a job choice or just to do some simple basic DIY layouts, how complex are you planning on going with your layouts... this info would help us to provide more focused information.
