Read this excerpt from a letter to the city council: Dear city council members:
The city has proposed limiting library hours in order to
save money. I understand that the city budget is being
challenged at the moment, but no good will come of
denying children access to the library after school.
Children go to the library to learn and to get help with their
homework. As a single parent, rely on the library as an
affordable place where I know my kids will be safe. Of all
the
programs to cut, the library should not be your first
choice.
