Maxwell's equations are of course the entire basis of modern electromagnetic theory. It is much easier to view these ideas here, in this brief form, than to wade through the 1873 and later editions of Maxwell's mammoth "Treatise on Electricity and Magnetism".
The primary benefit of this small volume is the easy access to this paper. One would otherwise have to go for a collection of Maxwell's papers, which would be somewhat more expensive. The preface to the volume is a useful addition to the work. However, the Introduction by Thomas F. Torrance is a bit over the top. It also introduces a bit of a Theological 'spin' to the material, which is not surprising when you see how many Theological/Religious texts this fellow is involved with.
Take or leave this 27 page introduction as you wish. The fact remains that you still get Maxwell, which is why you wanted the book in the first place!
