"A Passionate Publisher & A Collector's Zeal" has never been published, and is here first presented to give collectors (or potential collectors) a brief idea of how the Bishop Collection was assembled over the past decade, and to offer advice on collecting Mosher and other private press books.

The Bishop Collection details the scope and size of this extensive Mosher collection still in private hands, and discusses some of the highlights of the collection.

Various institutional collections of Mosher materials are also given to provide the researcher with details on Mosher material around the United States, and in Canada and England.
