I know by long experience that this set of many volumes is very informative. The collection adequately covers many sides of the doctrine of baptism. It really does help your wider understanding of the Bible itself to have studied these volumes.
Here is the link as best I know how to "copy and paste" it:

I have a number of these resources in hard copy in my personal library, but many of these volumes I have heard of and read about but do not have and cannot readily obtain.
Of the volumes I do have--on both the Baptist and non-Baptist side, I must say they have greatly informed my understanding of the Bible in many nooks and crannies which would otherwise have been unknown to me.
For example, the volume by Hibbard on Christian Baptism contains one of the best discussions I have read on the perpetuity of the ordinance of baptism. So What? you might ask. If you have not been reaching out to a wide enough audience of people about the Gospel, perhaps you have not encountered those who do not practice water baptism at all. If you carefully study their arguments (as I have), then study Hibbard--which I chanced to do, the issue is squarely settled once and for all.
I have much more to say about the value of this great collection on Classic Studies on Baptism.
My hope, though, is that you will reconsider and bid on this set. I did so in September of 2013, I think it was, and it has not moved much since then. It needs to go into production so we all can benefit.
