Increasing libraries’ relevance on the Web
OCLC network interface services can connect users searching on the Web—where most people start their search—to their libraries and, using a broad range of intelligence about objects, identifiers, people, places and institutions, provide unprecedented context around items libraries hold

It may not be overstatement to say that the
Web has become the most significant engine
driving change in the technology landscape since
the advent of the computer. Indeed, the information
industry today is in a period of disruption that may be
as significant as the introduction of the Web itself, says
Mike Teets, Vice President, Global Engineering.
The Web is the new computing platform and its
architecture demands a new approach to and a new
strategy for product development, Teets says.
“The computing environment has moved away from
large monolithic services where users start and end
their work in a single application. In that environment,
the design of the application was isolated and all attention
could focus on the single application. Now OCLC
services must be used inside workflows that involve
many applications.”
Thriving in this new network environment requires
developing network interface services, commonly
referred to as Web services or service-oriented architecture. These services are software components
that can be exposed on the Web using industry-wide
protocols, making it possible to quickly link together
computer systems across organizations worldwide. A Web service’s functionality and data are available
through a machine interface and can be reused within
other applications.
From a technology perspective, Web services
provide: more flexibility, better integration of existing
applications, reduced data replication and faster
application development. They also allow seamless
presentation and consumption of services across the
network and provide the capacity for:
-
data and service sharing across network nodes: local, regional and global;
-
functionality to be placed at the most appropriate
point in the network; and
-
all nodes to add value to, and gain value from,
the network.
OCLC Web services are exposed independent of
OCLC applications as well as assembled into OCLC
composite hosted services. They provide an open infrastructure
for building a Web-scale library service
in a view that’s appropriate for each library. They
will allow libraries to present themselves in a local,
regional or global view on the Web and bring searchers
to their content and services. The services allow
the automatic insertion of relevant context around the
objects searchers find.
“Right now, library databases, collections and services
are not in mainstream Web traffic flows—the
search engines and Internet services where the
majority of people start their search,” says Teets. “Library databases are flat. They require an expert to
navigate the relationships between sources, content
and structured metadata.”
Among the network services that OCLC
is developing:
-
Connexion. Many of the underlying components of
Connexion, OCLC’s flagship cataloging service, are
being developed as Web services, including validation
and terminologies metadata creation.
-
WorldCat Resource Sharing. OCLC’s new
WorldCat Resource Sharing exposes interlibrary
loan operations—create, search, retrieve and update
requests—in local ILL services.
Libraries and alternative service
providers that have implemented this
Web service are: MINITEX, Atlas
Systems (ILLiad), ILL ASAP, Perkins
and Associates (CLIO), the University
of Pittsburgh and the British Library
Document Supply Centre. Libraries
that use these applications can use
OCLC ILL at their point of need in
their environment.
-
WorldCat.org. This program is
comprised of a suite of services
that syndicate content and services,
provide various integration points and
operate inside many different environments.
-
WorldCat toolbars. These software components
work seamlessly with browsers and search engines to
make library searching an “always-on” option by mixing
Web search with Find in a Library—if it’s in a library
nearby, toolbars let searchers find it in WorldCat no
matter where they are on the Web.
-
OpenURL Resolver Registry. This Web service
brings together functionality from local library systems
and OCLC to route searchers to their libraries’
electronic full-text collections. The registry contains
location and configuration information about libraries’
OpenURL resolvers, which link metadata and
identifiers to a specific copy of an object. A gateway
matches registry information with the user and passes
through requests to the appropriate OpenURL
resolver. Together, the registry and gateway make
OCLC services interoperable with whatever OpenURL
resolver software libraries use and allow libraries to
express preferences and conditions that
govern the linking and display of their
online resources. And the library will need
to enter and maintain this information in
only one place.
-
WorldCat Registry. This is a
comprehensive directory for libraries and
consortia, and the services they provide.
It helps libraries and consortia manage and
share data that define their organizations
through a single, authoritative Web platform.
-
xISBN service. OCLC Research
created this Web service, which supplies
International Standard Book Numbers
(ISBNs) associated with individual works
in WorldCat, for anyone interested in linking an
application to it. Recently, this service was turned into
a robust web-scale application that can be integrated
into mainstream applications in the library environment.
An increased focus on Web services is essential for libraries
and OCLC to remain relevant to users, Teets says. “To be successful in this new network environment, OCLC
and library services need to interoperate with services
from alternative service providers, including those outside
of the typical library service industry. We may not own the
interface or the user relationship in every case so we must
architect for success.”
