If so, you'll surely love perusing the web pages located at Classic Crime Fiction. Extensive bibliographies, lists of award winners, remarkable art work from dust cover jackets, brief biographies of key authors, genre overviews, and more.
Among my favorites so far are the Haycraft Queen Cornerstones (the "Definitive Library of Mystery Fiction"), the Queen's Quorum a check list of the "125 Most Important Detective/Crime Fiction Books," and the short bios of Chesterton, Doyle, Marsh, and others.
Do check it out.
