One important measure of a robust democracy is the quality of its public libraries.

A public library is a place where any citizen, rich or destitute, can access a vast repository of knowledge, in one place, free of charge.

But times are changing. The rapid evolution of information technologies, especially that digital wilderness known as the Internet, has compelled libraries to evolve as well.

It's a challenge that will require some creative thinking by Richard Burns, the incoming head of The Hawai'i State Public Library System.

When Burns takes the helm next year, he'll face some familiar problems: A staff shortage of about 80 vacancies; enough operating money to maintain current services, but not to grow them; and an antiquated computer network.

Since the mid-1990s, the library system has lost more than 100 positions that it never regained. And the staffing shortages are expected to grow more acute as new libraries open over the next 10 years. While technology can help — self-service checkouts, downloadable e-books, online databases — there's no real substitute for well-trained librarians. A library is not just a building filled with books — it's what Burns calls "the source for reliable, accurate, peer-reviewed information," an authoritative collection of resources, in print and online, designed and managed by professionals to inform a democratic society. The quality of the library depends on the quality of its staff.

Public libraries also must have up-to-date technology. With vast amounts of information going digital, access depends on computers and the networks that connect them. To fulfill their public mission, libraries must continually invest in their computer networks. Otherwise, the information superhighway will be open only to those who can afford a computer and broadband fees.

With careful stewardship and adequate resources, libraries will continue to be what Burns calls "vibrant community centers emphasizing personal assistance, quality services and creative programming for all ages in a friendly, safe and enjoyable environment."

It's a worthy investment in the future of our democracy.
