Of these, Bartlett's Familiar Quotations, The Oxford Dictionary of Quotations, The Columbia Dictionary of Quotations, The Yale Book of Quotations and The MacMillan Book of Proverbs, Maxims, and Famous Phrases are considered among the most reliable and comprehensive sources.
As described in its introduction, The Yale Book of Quotations is characterized by its greater focus, relative to its nearest competitors, Bartlett's Familiar Quotations and The Oxford Dictionary of Quotations, on modern American quotations, including those that do not have conventional literary sources.
