Electronic Statistics: Counting Crows
While the public at large seems to have good feelings about their libraries,
it has become increasingly crucial for public libraries to go to their
boards, their city councils, and other groups who control the purse strings
with numbers in hand. Those numbers need to show growth: more people using
more of the librarys resources. It is relatively easy to count circulation,
whether of books, videos, or other materials, and rather less easy to
count reference questions or telephone inquiries. However, the advent
of electronic access, electronic databases, and e-reference has created
a multitude of services not so easily quantified. These numbers may be
as elusive as the flocking crows of the titles musical reference. Fundamentally,
however, standardizing and counting electronic statistics is most important
for libraries themselves: to know who is being served, and how much, to
know what to plan for, and what is desired.
The Public Library Association has studied, standardized, and quantified
output measures of service in the past. Public libraries are now poised
on the cusp (or perhaps on the brink) of resolving a number of interrelated
issues concerning electronic statistics. This Tech Note serves as a pointer:
these ideas and policies are in development, not available as of this
writing, but the projected dates of completion and places of publication
are given in the last paragraph.
What are electronic statistics for?
Concern for counting electronic crows indeed grew out of the increase
in electronic resources. However, it was the study and effort that went
in to defining and measuring other public library statistics that laid
the groundwork for these questions. Jay Burton, Head, Library Programs
and Development, State Library of Ohio, in Measuring
Library Services: The Ohio Project focuses on the Projects concern
with two major weaknesses in public library statistics in general: inconsistency
in reporting, and failure to address electronic access. Burton outlines
the questions: what should librarians measure? How can it be done efficiently?
And what do we do with the information once we have it?
Burton also succinctly describes why it is important that we take such
measurements. The reasons include:
- demonstrating good use of public funds
- assisting in planning for goals, objectives, and future technology
- feedback on the efficacy of specific library services
- providing the public with a clear understanding of what libraries
do for the community.
Burton urges the identification of library services to be measured, identification
of measures of service, and definition of procedures for gathering data.
Judith Hiott of Houston Public and of the PLA
Research and Statistics Committee focuses on electronic statistics.
She and the committee define them in two forms:
- measures of availability
- measures of usage
Measures of availability include number of workstations, number of licensed
electronic resources, and number of hours of access available. In turn,
these can be broken
down for more extensive analysis. This breakdown would include, for
example, under number of devices in the outline, items such as
in-library resources, licensed external resources, and number of general
Internet portals. Other breakdowns might include counting electronic resources
by whether they are index only, index and abstract, and/or full text,
and whether these resources are available only on site in the library
or by remote users from their homes or offices. Hours of access can then
also be counted even when the library isnt open, if people can use
them 24/7.
Measures of usage at the baseline level are number of log-ins/sessions,
number of searches, and number of items examined (viewed/downloaded/printed).
These in turn can be broken down by database, by time, by title, and so
on, including peak number of simultaneous users.
Breaking down and analyzing the electronic numbers offers a library,
and by extension its public and its funding agencies, a far clearer picture
of what library resources people are actually using, creating part of
the benchmarks for collection development, planning, and future technology.
How are electronic statistics developed and defined?
The work done by Hiott and Burton (and others) is based in part on a
document produced by the International Coalition of Library Consortia
(ICOLC), Guidelines
for statistical measures of usage of Web-based, indexed, abstracted, and
full text resources, November 1998. These guidelines in turn were
based heavily on the work of the JSTOR
Web Statistics Task Force, in a very pretty model of not reinventing
the wheel. (JSTOR
Redefining Access to Scholarly Literature is now a not-for-profit
organization, founded to provide electronic access to long runs of core
scholarly journals.)
John Carlo Bertot and Charles McClure are conducting a study called Developing
National Public Library and Statewide Performance Measures begun in
January 1999 and to be completed in May 2000. Bertot and McClure intend
to develop a core set of national statistics and performance measures
that librarians, researchers, and policy makers can use to describe public
library and library-based statewide network use of the Internet and Web-based
services and resources. In the Public Libraries article cited
in the bibliography, Bertot and McClure stress that it is better to collect
a few specific electronic statistics than none at all. They encourage
libraries to at least begin.
It is crucial that electronic statistics and the methods used to describe
them be consistent in meaning and methodology. In an email, the director
of a public library in Massachusetts notes the difficulties across various
vendor platforms of collecting statistics that actually measure the same
things. Database vendors do supply statistics, but they are not defined
consistently and do not necessarily count what libraries may need numbers
on.
As the electronic crow flies
PLAs Research and Statistics Committee, the outline of whose report
and charge is on the web, will publish a complete report, probably
in Public Libraries magazine, to be written by Diane Mayo. Judith
Hiotts article in the October 1, 1999, issue of Library Journal
covers practical aspects of electronic statistics gathering at the Houston
Public Library. Their work, the work of Burton and others in Ohio, and
the scholarly study of Bertot and McClure will give librarians good tools
for counting those elusive crows.

The Public Library Associations Tech Notes project grew
out of the desire to continue the work of Wired for the Future: Developing
Your Library Technology Plan, by Diane Mayo and Sandra Nelson, published
for PLA by ALA in 1999. Each of the Tech Notes, written by GraceAnne A.
DeCandido, is a Web-published document of 1,5002,000 words, providing
an introduction and overview to a specific technology topic of interest
to public libraries at a particular point in time. Topics were identified
by PLAs Technology in Public Libraries Committee. Each Note is marked
with the date of its completion and posting, and with the date, approximately
one year later, when links and other information were reviewed.
The Technology for Public Libraries Committee
is currently evaluating if the Committee should request PLA funding for
additional Tech Notes. Readers comments and suggestions are welcome and
should be addressed to pla@ala.org. Please
use Tech Notes in your subject line.
