Barry library will open on August Bank Holiday Monday, thanks to its latest technology which makes it possible for the library to open without staff members.
The library will be open from 10am – 4pm for adult registered library members who have opted into the Open+ service.
Open+ is provided by Bibliotheca, a company which provides self-service solutions for libraries around the world.
The late night opening is designed to complement the core staffed hours by extending opening times to provide access for people who cannot use the library during the day.
The service first began in April, and over 100 people have already used the library facilities during the late night opening hours.
The service has been operating successfully to provide unstaffed additional hours until 9pm on weekdays since April this year.
Barry library is the first branch in Wales to trial the late night hours, using Open+ technology.
If the bank holiday trial is successful, it will be considered for other Bank Holidays during the year.
Anyone who would like to use the library on Bank Holiday Monday must be a current or new library member and sign up for the service in advance.
Library members must register for the service and will be given a pin number allowing them late night access. Members must complete a short induction before using the card.
Photo ID is required to sign up to the service and if residents are not already a library member they will need to provide evidence of name and address.
