When councils cut their budgets, it's always libraries that have the spotlight put on them. As staff hours and numbers are cut, librarians are overcoming their reluctance to whisper about the value of their services.

The value of libraries goes well beyond a book repository, and librarians are asking local body politicians who haven't stepped inside one for a while to take a good look at what they do.

Times are tight, for local councils as much as anyone, so it's not surprising they're running a ruler over all their services.

That includes libraries.

From Auckland's Wayne Brown suggesting they could be staffed by volunteers; to Christchurch's Phil Mauger saying last month that community libraries were just "buildings with some books in them" as he proposed shutdowns; these community facilities seem to always bear the brunt of cost cuts.

Reduced hours, staff redundancies, and closed doors on Sundays have all been on the agenda.

"We can watch something on TV, we can watch movies, but the pictures are provided for us. But when we read a book, it's all in our mind."

Riley points out that books are very expensive, and the people who go into shops to buy them are not likely to be young brown people, or anyone from a low socio-economic background.

"Where are they going to get books from? It's the library that provides books for free. If you take away that, our population is going to become dumb. It's the one place where people who can't afford to buy books can experience the joy of reading."

One-in-three New Zealanders hold a library card and are active library users, says the president of the Library and Information Association of New Zealand Aotearoa (LIANZA) Richard Misilei. …
