Virtual Reference
Service and Disservice
by Péter Jacsó
This issue deals with many of the organizational, financial,
and technical issues related to virtual reference services.
I'll focus on my favorite aspect, making better use of
high-quality digital reference resources in the virtual
context, and present the case for my longtime pet project,
developing my PolySearch Engine to cross-search the best
reference resources of my choice in one fell swoop. Such
solutions may help us move beyond first- and second-generation
digital reference mind-sets and approaches.
A Look at the First and Second Generations
In the early days of the Web, librarians just bookmarked
their favorite online reference sources in order to
get to free and subscription-based dictionaries, encyclopedias,
and almanacs quickly. These were usually good-quality
sources, as librarians themselves used them. Librarians
also happily shared the URLs of the relevant sites
with their patrons if they cared to know. Then came
second-generation digital reference, clearly motivated
by the desire to cater to the needs of "virtual patrons" who
did not show up at the reference desk, but instead
logged into the library sites looking for sources of
ready-reference information. These patrons could even
have been in the library but sitting at the terminals,
not waiting in line for their turn at the reference
desk. From the reference librarians' perspective, they
were no-shows.
The first step to help the no-show users was to enhance
the online public access catalog with the URL of the
(local or remote) digital version of a print publication
that was held by the librarysay, the Columbia
Encyclopedia. This was fine but not prominent enough;
more importantly, it was not applicable for the Web-born
ready-reference resources that had no print counterparts,
or at least none at the library.
Librarians found a good compromise by listing such
resources on a special Web page on the library site,
indicating if a source was generally available for
the public or only for a select group of people (like
card-carrying members). Many libraries and independent
information professionals have been offering superb
link collections to high-quality reference sources
for years. I paid homage to many of them in the May
2001 issue of Computers in Libraries.
The problems emerged when lay people (sometimes well-intentioned
but lacking competence) posted lists that included
any warm bodyer, resourcethat touted the
words encyclopedia or dictionary or almanac, or a part
of these words, as in Atlapedia (aka Geopedia). When
the word free also appeared in the title or prominently
elsewhere on the site, it guaranteed a spot on thousands
of link lists and in classified directories, including
the best ones like Yahoo!. In the search engine results,
these linked sites drowned out the really useful ones,
which may not have had one of these magic words in
their titles, title fields, or URLs (like World Book
when it was available for free throughthe Discovery
site). They received fewer links, and hence ranked
less relevant in the results lists.
Providing a Virtual Reference Disservice
The real disappointment for me was seeing many library
Web sites include in their (implicitly endorsed) link
lists such inferior sources as the Free Internet Encyclopedia
(which is not even an encyclopedia but a collection
of links to other sites, including good encyclopedias,
for articles about very randomly and illogically selected
topics), Nupedia (which even TheNew York Times gushed
about when it had only 10-12 articles, and which still
has only 25 articles as of February 2003if we
count the short and long versions separately), and
Atlapedia, a collection of maps with country profiles,
whose modern history sections end in 1993, and whose
other statistics also often lag much behind the vital
statistics available through, say, the World Factbook.
Sending virtual patrons to such sites is a reference
disservice. It adds insult to injury when library sites
don't include links to several worthy and free digital
reference sources such as xrefer, InfoPlease, Concise
Encarta, the Columbia Encyclopedia, or the Britannica
Concise at Yahooligans!.
Including a sorry encyclopedia in a list is less
of a concern when the good ones are in overwhelming
majority. Too many links, however, may lead to other
problems.
Virtual Referral Versus Virtual Reference
Often, I have the impression that the librarians
who include links to such poor sites may have never
used them themselves, but rather have borrowed them
from others' link collections. Had they used them,
they would have found out that many of them have not
only odd scope and shallow coverage, but also an extremely
large proportion of dead links. The Free Internet Encyclopedia
provides the perfect example.
There, I tried to look up the entries under the letter "Z," and
there was not a single one. The entries under the letter "Y" illustrate
equally well the typical troublesome editorial choices
in this source. (See Figure
1.) I don't need to yak much about the
absurdity of including an entry for yak and another
for Tibetan yak (both of them dead links), but none
for the many important people, geographic areas, etc.,
that start with "Y."
How come so many library Web sites link their patrons
and visitors to such a resource? The virtual and often
anonymous nature of such referral does not have the
embarrassment factor of face-to-face transaction. Of
course, a library would nevercarry (nor would The
New York Times waste a column on) a promising print
encyclopedia at its very early manuscript phase, sporting
merely a dozen articles. (For perspective: Britannica
Concise has 25,000 articles, most of them excellent,
except forthe currency of less than 1 percent of the
articles.) An experience with such an obviously inferior
source, endorsed by a link from the library site, would
discourage users. How many of them would follow other
links? Would they know which ones were more promising?
I doubt it.
Most of the library link collections are not annotated,
or they just regurgitate the publisher's blurb instead
of providing a substantial andif neededcritical
summary. I have yet to find a link to the Yahoo! and
Yahooligans! versions of Britannica Concise that warns
you that it is not updated as frequently as the version
provided by the original publisher (which is subscription-based,
except for the free headwords and first sentences of
the articles).
In the Yahoo! version, George W. Bush is still a
governor, East Timor is still a province of Indonesia,
and Billy Wilder is still alive (see Figure
2a). Even the headwords and free lead
sentences in the original publisher's edition would
provide you with the current information, calling George
W. Bush president, East Timor a country, and Billy
Wilder dead (see Figure
2b). Similarly, I have not yet found a
link to the encyclopedia.com site that correctly identifies
that it has offered the most current, 6th edition of
the Columbia Encyclopedia for more than a year. Most
of the annotated links claim that it offers the much
older and much smaller Concise Columbia Encyclopedia.
Providing a Real Reference Service Virtually
I think the best solution is to offer multisearch
engines for the most commonly needed and best ready-reference
sources, organized into genre groups (i.e., for general
encyclopedias, monolingual English dictionaries, bilingual
dictionaries, quotations, and biographies) that could
be searched with a single query in one fell swoop.
Savvy Search (now Cnet.com), Profusion, and Researchville
are on the right path, but they still have very limited
coverage.
I have been working on a solution (I call it the
PolySearch Engine) to run a simple query against several
reference databases for quite some time myself, and
as an extra feature to this column I have posted the
beta version of the PolySearchBiography module
at my site (http://www2.hawaii.edu/~jacso/extra).
(See Figure 3a for
my search template.)
PolySearch will not help the lack of information
about who received the 2002 Nobel awardsincluding
Imre Kertész for literaturein the A&E
Biography, the Biographical Dictionary, and even in
the otherwise current Encyclopaedia Britannica. But
users will likely be happy to find articles about Kertész
in Concise Encarta and the list of all the 2002 laureates
in InfoPlease, in one fell swoopwithout having
to follow links to the individual sources, find the
query templates, type the queries into each of the
sources one-by-one, or possibly even give up after
trying three sources in vain (see Figure
3b).
This Biography PolySearch will be followed (slowly)
by modules for other ready-reference source types (encyclopedias,
dictionaries, country profiles, atlases). They will
remain humble efforts software-wise, but will allow
anyone to type in simple queries (names, words, or
phrases like "highest infant mortality rate") and run
them against several of the 10 to 15 sources that I
found the most relevant for the categories. I think
this is the best contribution I can make to improve
some aspects of the reality of virtual reference services
