Do not lie to the librarian

Via Florida bookperson Erin Mitchell, the rules in force at the Hyde Institute library, Barnet Vale, Hertfordshire, in 1930:

LIBRARY USERS IN FUTURE MUST NOT:
Enter the library if their faces are offensively dirty.
Fall asleep on the tables.
Eat their lunches whilst reading papers, books, &c.
Smoke in the building.
Leave their business cards behind.
Make themselves a nuisance.
Kick or damage the furniture.
Tell lies to the librarian.
Enter when they are in an inebriated condition.
If they have small-pox.
