The Monroe County Library System branches are closed to in-person visits until further notice. While our physical locations will be closed due to safety concerns regarding COVID-19, the libraries will continue to serve the community. Library staff will be available by telephone Monday through Saturday from 9 a.m. to 5 p.m. for reference, renewal of material, and assistance for new users in the creation of an E-Library card. The E-Library card will allow users to access the library system’s digital collection and electronic resources. The “Ask-a-Librarian“ service will be expanded to provide reference services via chat and email. Librarians will provide, using the branch’s respective Facebook Live and website pages, daily virtual programmings such as storytime, book talk on our digital collection, and training sessions on our digital resources. Drop boxes will remain open at all locations and late fees will be suspended. Contact your local branch library or visit the library website at for additional links and information.

Monroe County Library System is the Oldest in South Florida

In 1853, the Florida Keys first public library opened in Key West. Today, Monroe County’s libraries are as popular as ever, with more than 350,000 adults and children visiting the five branches.

The libraries’ main mission is to meet the changing needs of the patrons for information, education, and entertainment. To do so, the library provides books, periodicals, and audio and video materials for circulation, both in print format and through electronic access.
