A “book and collect service” will be offered to customers by 90 libraries from Monday, July 20.
People will be able to order a collection of books via telephone and arrange for contactless collection.
All libraries here closed on March 20 due to the Coronavirus pandemic.
Also as part of the pilot scheme, five libraries will fully reopen for book browsing and limited IT access at the end of the month.
One of those is Derry Central library which will reopen to the public on Thursday, July 23.
Libraries NI said the pilot scheme would test how to keep customers and staff safe while learning how to reopen other local libraries as soon as possible.
The number of people allowed in at any one time will be limited and customers will be asked to limit browsing to 30 minutes.
In order to prevent the spread of Coronavirus, returned books will also be stored for a period of time in each library before being returned to the shelves.
With preparations now in place for reopening Libraries NI has asked customers to return books they loaned before lockdown, with collection times available on their website: https://www.librariesni.org.uk/Pages/default.aspx
