Relating to or concerned with the study and description of books, their authors, publication details, and history.
From biblio- (Greek biblion 'book') + -graphical (Greek graphia 'writing, description'). The term emerged in the 18th century as book collecting and cataloging became systematic scholarly pursuits.
Bibliographical study helps us understand not just what a book says, but why it was printed the way it was—the paper quality, typeface, and binding can reveal forgeries or show how knowledge spread through the medieval world.
