From Wednesday, August 12, appointments can be booked to use the Six of the Best Service or a slot for the Browse and Borrow Service from August 19, at the libraries.
The Browse and Borrow Service means that customers are able to come into the library for a pre-booked 30 minute period and choose up to 20 books.
Customers using the Six of the Best Service can collect a selection of up to six books chosen by library staff at a pre-booked appointment time.
County Councillor Peter Buckley, Lancashire County Council’s cabinet member for community and cultural services, said: “It is such good news that we are now able to welcome our customers back into 14 more of our libraries.”

Appointments can also be made by calling 0300 123 6703.
As other libraries will remain closed for now, customers can make an appointment to visit any of the libraries that are open, even if it isn’t their local library.
Anyone wanting to return books can do this by placing them in the returned books container at the entrance of the libraries that are open.
Customers will not be charged for any overdue items. Library users are being asked to hold onto their books until they can return them to an open library and not try to post them through letter boxes or leave them outside libraries. Books can be renewed online or by calling 0300 123 6704.
