Oakland: The Public Library: Notes 1
- Great care is taken to prevent books from spreading contagious diseases. The collections are renovated continually. Soiled and worn books are discarded or rebound and thousands are annually washed page by page with a solution of ammonia and water. Moreover, the bureau of health sends to the library a daily report showing the houses in which there are contagious diseases. Books taken out by readers in those houses are collected by the library messenger and burned.
