"It's something that we feel that we need to do to be ready for the next wave of changes."
Mrs Hawker said staff have been tagging the books since late November. They're also having a clean out of the collection. This will ensure the collection meets the current and future needs of Masterton users.
"The books that are disappearing off the shelves are books that people aren't using and haven't used in a long time," she said.
There have also been changes with the library's digital services.
Team librarian digital services Jeremy Langley, said the libraries digital services became increasingly popular during the holiday season, as many people brought in new devices and asked about e-books.
He said the new online BookPsychic service programme, which recommends items from the collection that are tailored to a borrower's reading tastes, has increased in popularity. The online services have enabled users to access the library whenever and wherever they want.
"For those people whose time is now limited they can stay home and find exactly what they want. The only time they need to come to the library is when they need to collect their item," she said.
The library has also had a temporary later opening time of 10am, to allow staff the time to tag the books.
