SELF-service terminals are being installed at Chichester library.
West Sussex County Council says they will speed up transactions, cut down on queues and allow staff to make better use of their time.
The terminals will be in installed after the library, in Tower Street, closes temporarily from 7pm on Friday.
It will reopen on Monday, October 31 at 9am.
Council leaders stressed that no staff are being made redundant through the new system, known as Radio Frequency Identification.
Deputy leader Lionel Barnard said the only change to staff was achieved during the library service restructure in March, when a vacant post was removed.
He said: ‘The self-service system allows you to borrow and return your loans quickly and easily. You just follow the instructions on the simple step-by-step screen, or a member of staff will be on hand to help.
‘You can even print a list of what you’ve borrowed, check when an item is due for return, and make any cash payments.’
Plans are also afoot to install the terminals at Bognor Regis library.
People can still borrow up to 20 items before the temporary closure of the library at Chichester.
