Noonan's book is a good source for patristic quotes, you just have to take the quotes out of the framework in which Noonan places them (for example, Noonan believes that the early Church's view against contraception was derived not from Scripture or Tradition, but Stoicism). Once you take them out of Noonan's framework, though, they are pretty easy to examine using sites like CCEL. I would not recommend any of the other books I've read on the subject, except the David Ford book I mentioned earlier in the thread, which is about sexuality in St. John Chrysostom, but also touches on many other (especially Western) Fathers in the first chapter or so.
