With all the Calvin resources in pre-pub, this would be a good book to also have in Logos:
"The Writings of John Calvin, Expanded Edition: An Introductory Guide" by Wulfert de Greef (translated by Lyle D. Bierma)
Carl Trueman (of WTS) has this to say in his review:
"It is exactly what it says it is: an introduction to the life and
writings of the Genevan Reformer and is, as far as I am aware, without
peer in the field.
The book consists of ten chapters, covering
Calvin's life and works, plus a survey of primary sources, a select
bibliography of secondary literature (not confined simply to
English-language resources), and a chronological index of Calvin's
writings. In short, there is a wealth of valuable reference material
here that one will not find as conveniently or concisely assembled and
arranged in any other book.
....Indeed, it is hard not to sympathize with Jon Thompson's jacket
commendation that indicates that the pastor or scholar really needs two
copies: one for the office and one for home. Thoroughly recommended."
