Free books by brethren

The Stone Publishing Trust is advertising the following:

We have a large amount of second hand ministry for redistribution including some by J.N.Darby, F.E.Raven, J.B.Stoney, C.A.Coates, J.Taylor Snr, and a variety of other of the Lord’s servants. Complete sets are available for some but also single volumes. It is our wish, and that of the donors, to get these books into circulation again and they are offered free. A contribution to postal costs would be appreciated. 

You can find the page here. Of this  list of author's names, I've only read material by Darby and Coates. Everyone says that Darby is hard going, and they are right, though the effort is certainly worth it. But I am very much enjoying Coates's book, The Believer Established, and would certainly recommend it as something which any Christian could read and find helpful.
