Anyone using Clackmannanshire libraries or CAPs on Saturday 4 February will be entered in a prize draw to win vouchers of their choice to the value of £25, £20 and £15.
The three prizes are being presented as Clackmannanshire libraries take part in National Libraries Day, which is designed to raise awareness of libraries, encourage more people to join and experience what local libraries have to offer. The theme of the day is 'Use it, Love it, Join it'.
Library staff are also involved with other promotional activity, including Bookbug costume visits to local nurseries and holding Bookbug sessions in Alloa twice a week.
The National Libraries Day will be a celebration of the work done in schools, colleges, universities, workplaces and public libraries to promote learning, literacy and the enjoyment of reading to all. It is supported by a range of organisations including the Chartered Institute of Library & Information Professionals, the Reading Agency, the National Federation of Women's Institutes, library campaigners and publishers.
Twenty-three of the country's most outstanding writers, including Julian Barnes, Alan Bennett and Stephen Fry, have also contributed to The Library Book, in which they describe libraries real or imagined, past, present, and future - why they matter and to whom.
Depute Leader, Councillor Mark English, said: "We want to encourage library users, new and old, to go along to their local library and find out about the many services on offer. Your local library is the place you can choose a book, use a computer, find out about local history, do research, attend literary events, access community facilities and so much more."
