On A Much Lighter Note

Here is an advertisement that the lovely Ruth pulled out of one of our local papers circa Dec. 16, 1901:

To Library Patrons.
Patrons of the public library are urged to call for books on other days than Saturday, before four o'clock in the afternoon. After four school children apply for books in such numbers as to test the issuing capacity of the library and those who desire books can only get prompt service by calling early, while at the same time the labors of the librarian may thereby be lightened.

I don't know what's wilder, the concept that someone could advertise that and have people listen, the idea of children rushing to the library for books, or the presence of only one librarian.
