Masterton District Library staff have tagged about half of their 60,000 books, DVDs and other items as they prepare to make the library more user friendly.
The books are being RFID (radio frequency identification) tagged which will speed up the issuing and returning of books through a radio frequency aerial "pad".
The system, which allows users to issue their own books, is being introduced at the same time and it will free up staff to assist with user enquiries.
Customer services librarian Chris Hawker said they are about halfway through the collection of about 60,000 books and were pleased with their progress.
"It's about making more time for us to be more available to assist people with what they require," she said.
