Guernsey's public libraries have closedpublished at 10:40 GMT 23 March 2020
The Priaulx library closed on Saturday followed by the Guille-Allès Library on Sunday.
Sue Laker, chief librarian at the Priaulx Library, said anyone with books on loan should "continue to enjoy them at home".
She said they can returned once the library reopens and outstanding fees would be waived.
A spokesman for the Guille-Allès Library said: "Nothing is more important to us than the health and wellbeing of the public and our staff, and we are now convinced that closing the doors is the best way we can help keep everyone safe."
The number of times an item can be renewed has been increased from eight to 20 so no books need to be returned while it is closed.
The spokesman said those with a library card can access "huge digital collections of eBooks, audiobooks, newspapers, magazines and other resources" for free. Anyone who is not a member can sign up online.
He said they were working on growing those collections, moving more events online - such as Rhyme Time Live - and expanding its home delivery service for the over 70s.
Both will provide further updates on their websites and via social media.
