The world´s largest fine for an overdue library book is $345.14 (£203.29), the amount owed at two cents a day for the poetry book Days and Deeds checked out of Kewanee Public Library, Illinois, USA in April 1955 by Emily Canellos-Simms. Although the book was due back 19 April 1955, Emily found it in her mother´s house 47 years later and presented the library with a check for overdue fines. (Source: Guinness World Records)
