The Multnomah County Library provides a variety of services to citizens of the

county. First, the library offers a number of traditional books and movies that may

be checked out by patrons. Each patron may check out up to five books and two

movies at one time. The library also offers several computers for patron use. The

library tracks computer use sessions. Each patron may use the computer for up

to $30$ minutes per session. The library also maintains a number of small meeting

rooms that patrons may reserve for classes or events during normal operating

hours. Although library services are offered to all county citizens, each patron must

obtain a library card to check out books, use the computers, or reserve a room.
