What
is LinkSeeker?
LinkSeeker is a new tool that enables context-sensitive linking
between electronic resources. For example, upon searching Inspec�, you discover
that for each of your search results, LinkSeeker presents a number of options
for further navigation within the Research Library's collection and beyond.
For the first reference you consider, you note that there is a link to the full-text
of the article. Another link allows you to conduct a cited reference search
in SearchPlus, yet another one links into the Research Library's online
catalog. You follow the link into SearchPlus and, again,
LinkSeeker buttons appear for each of the search results. One goal
of testing is to determine what other services you would find valuable.
Originally called SFX, the
LinkSeeker framework was developed from research on linking between
scholarly information resources, including full-text repositories;
abstracting, indexing, and citation databases; on-line library catalogs;
and citations appearing in research articles, e-print systems, and
other Web resources. This framework permits context-sensitive linking
between Web resources; it is context-sensitive in that the target
of a link within the framework depends on the digital library collection
of the institution to which the user who requested the link is affiliated.
This is accomplished by installing a mechanism--a "hook"-- that
allows other servers to intervene dynamically in the selection of
a link's target. The presentation of available links is fully determined
by the local library presenting the services, and is constructed
by examining available metadata within a database record as the
user clicks on the LinkSeeker button.
This project from the Library Without
Walls Project and the LANL
Research Library is made possible with co-operation from
Ex Libris, a developer of high performance applications for
libraries and information centers. The SFX context-sensitive reference linking
solution was acquired by Ex Libris from Ghent University in Belgium.
Use of LinkSeeker is limited to staff of LANL and other
subscribing institutions. Institutions interested in subscribing should see the
library Electronic Products page for more information.
