The Boke of Saint Albans.

Chapter II. Typography and Bibliography
Old books must be loved, and their indiosyncrasies carefully studied, before they yield up all their treasures; that done, the observant lover will obtain possession of both soul and body; he may revel in the intellectual feast provided by the author, or he may study the material and mechanical features of the books as represented by the peculiarities of the paper and the habits and customs of the various printers. Then, by grouping these as a botanist does his flowers, according to their organisation into classes, orders, genera, and species, he may extract from his volumes true replies to questions which would remain hidden forever. So true is the dictum, "The Mind it is which sees, and not the Eye alone."
