On the supply of printed books from the library to the reading room of the British Museum

In the first pages the reader is drawn into a lively dispute over the seemingly mundane rules that govern a great public library. Sir Nicholas Harris Nicolas insists that accurate tickets and press‑marks are not mere bureaucracy but the very lifeline that lets scholars reach the books they need. He warns that any lapse belongs to the patron, not the museum staff, and frames the whole enterprise as a matter of public responsibility. This brisk opening sets a tone that is part history, part courtroom drama.

The author then unpacks the intricate system of cataloguing that underpins the British Museum’s collection. By explaining how press‑marks locate a volume within a maze of presses, shelves, and volumes, the narrative reveals the practical challenges faced by both attendants and readers. A reform introduced in 1836—adding the same reference marks to the Reading Room catalogue—promised to cut waiting times, reduce errors, and ease the burden on staff. Through a selection of original correspondence, the book illustrates how a seemingly small administrative tweak could transform the experience of every visitor to the reading room.
