Library technicians in school libraries work regular school hours. Those in public libraries and college and university (academic) libraries also work weekends, evenings and some holidays. Library technicians in special libraries usually work normal business hours, although they often work overtime as well.

The schedules of library technicians who drive bookmobiles depend on the size of the area being served. Some bookmobiles operate every day, while others go only on certain days. Some bookmobiles operate in the evenings and weekends, to give patrons as much access to the library as possible. Because library technicians who operate bookmobiles may be the only link some people have to the library, much of their work consists of helping the public. They may assist handicapped or elderly patrons to the bookmobile or shovel snow to ensure their safety. They may enter hospitals or nursing homes to deliver books to patrons who are bedridden.
