The library in the internet age

You’d be surprised that it hasn’t outlived its usefulness

| DONALD A. BARCLAY | U.S. institutions of higher education and U.S. local governments are under extraordinary pressure to cut costs and eliminate from institutional or governmental ledgers any expenses whose absence would cause little or no pain.

In this political climate, academic and public libraries may be in danger. The existence of vast amounts of information – a lot of it free – on the Internet might suggest that the library has outlived its usefulness.

But has it? The numbers tell a very different story.

In spite of the findings of a survey in which Americans say they are using public libraries less, the usage numbers reported by libraries indicate the opposite.

Some upward trends

In the last two decades, the total number of U.S. public libraries slightly increased – inching up from 8,921 in 1994 to 9,082 in 2012 (a gain of 2.14 percent). Over the same period, the data also show that use of public libraries in the U.S went up as well.

Here’s what data on circulation (books and other items checked out to library users) and annual visits to public libraries reveal.

The number of books and other items borrowed from U.S. public libraries increased from 6.5 items per capita in 1993 to 8.0 items per capita in 2012 (up 23 percent). Over the same time span, the number of visits to U.S. public libraries rose 22.5 percent.

The one major public library usage measure that did decrease was the number of times library users asked questions of reference librarians, dropping 18 percent from 1993 to 2012.

The popularity of U.S. public libraries is, it seems, at least as strong as it was before the web became a household word (much less a household necessity).

Rise of the e-book

For academic libraries, the data are more mixed. Circulation of physical items (books, DVDs, etc.) in U.S. academic libraries has been on a steady decline throughout the web era, falling 29 percent from 1997 to 2011.

That fewer books are circulating is hardly a surprise given the vast amount of scholarly information (the bulk of it purchased with academic library budget dollars) that is now available to students via their electronic device of choice.

Electronic scholarly journals have driven their print-format predecessors to obsolescence, if not quite extinction, while e-books have become increasingly plentiful.

In 2012, U.S. academic libraries collectively held 252,599,161 e-books. This means that over the course of about a decade, U.S. academic libraries have acquired e-books equal to about one-fourth the total number of physical books, bound volumes of old journals, government documents and other paper materials acquired by those same libraries since 1638 – the year Harvard College established the first academic library in what is now the United States.

E-books are not only plentiful, they are popular with academic users (in spite of some shortcomings in usability). For example, data provided to the author show that when the University of California, San Diego made a collection of academic e-books available to students and faculty through the popular JSTOR interface, the usage numbers proved impressive.

In just under a year, UCSD students and faculty used 11,992 JSTOR e-books, racking up 59,120 views and 34,258 downloads. In response to user demand, the UCSD Library outright purchased over 3,100 of the titles offered via JSTOR, making those e-books a permanent part of the UCSD library collection.

Who needs the encyclopedia?

As with circulation numbers, reference questions asked of librarians in U.S. academic libraries have undergone a sharp decline – standing now at 56,000,000 per year, down 28.4 percent from 16 years ago. For the 60 largest U.S. academic libraries, the average number of reference transactions dropped from 6,056 per week in 1994 to 1,294 per week in 2012 (down 79 percent).

There’s not much mystery behind the drop in reference transactions. When I first began working as an academic reference librarian in 1990, hardly a day went by when I didn’t put my hands on such reference works as Places Rated Almanac, The Statistical Abstract of the United States and College Catalogs on Microfiche to answer reference questions.

Today, students access information digitally. The Google app on their smartphones allows students to look up information they once would have found only in analog, library-owned reference sources. And as for that old reference warhorse, the printed encyclopedia – Britannica churned out its final set in 2010.

Further contributing to the decline of in-person reference service is the fact that students are increasingly able to consult with academic librarians via the Internet.

By 2012, 77 percent of U.S. academic libraries were offering reference services via email or web chat. Currently, over 400 academic libraries provide around-the-clock, chat-based reference service as members of OCLC’s 24/7 Reference Cooperative, a global library cooperative that provides shared technology services.

Given only the above numbers, the hasty conclusion would seem to be that everything is online and nobody uses academic libraries any more.
