There is probably no series of books that has had more influence on me than the Puritan Paperbacks. They are all good. This one, however, is probably the best one to keep on your shelf as a reference (along with Vincent's "The Shorter Catechism Explained From Scripture").
There are two others that are also compilations of quotations ("Flowers from a Puritan's Garden," "Smooth Stones from Ancient Brooks"), the former being sermon illustrations by Manton expanded by Spurgeon, and the latter quotations from Brooks, again, gathered by Spurgeon. But those quotations are limited to only those two Puritans, and neither is arranged topically.
In contrast, this volume extracts 1500 quotations from almost 150 Puritan authors, and arranges them topically. The most frequently quoted authors are Watson, Gurnall, Thomas Adams, Baxter, Brooks, Swinnock, Owen, Trapp, Flavel, Henry Smith, and Manton, in that order. The quotations are selected for their brevity, intrinsic value, and thought-provoking quality. Highly recommended.
