The following public domain book is now available on-line in PDF:
H.N. Bate, History Of The Church to A.D. 325, 2nd edn. London: Rivingtons, 1924. Hbk. pp.140.
I remember finding this book extremely helpful when I was studying church history and so was pleased to find that the copyright has expired. It can now be downloaded from here.
