Others - including the sites serving Yaxley and Whittlesey - won't be opening until August.
Online reservations will be available from June 29, with customers able to call or contact the libraries online to request specific titles, or a selection of books based on genre or author. There will be no browsing of titles allowed, nor any borrowing of CDs or DVDs.
Access to IT facilities will be by appointment only, with one 45-minute appointment per day per customer.
All in-library events are still on hold and room hire remains unavailable.
For customers who borrowed items prior to lockdown, due dates have been extended until September 30. These can be returned to any open library before this date.
The loan period has been extended from four weeks to six weeks on a temporary basis for any item borrowed in July and August. Reservation charges have been suspended and loan charges remain frozen until August 31. This date will continue to be under review.
