Coordinating Editor Tim Lepczyk salutes change in this issue, welcoming new
editors to the Journal and announcing his departure.
Tools for Reducing and Managing Link Rot in
LibGuides<http://journal.code4lib.org/articles/7019>

Wilhelmina Randtke and Matthew D. Burrell

While creating content in LibGuides in quite easy, link maintenance is
troublesome, and the built-in link checker offers only a partial solution.
The authors describe a method of using PURLs and a third-party link checker
to effectively manage links within LibGuides.
Discovering Digital Library User Behavior with Google
Analytics<http://journal.code4lib.org/articles/6942>

Kirk Hess

Google Analytics has advanced features for tracking search queries, events
such as clicking external links or downloading files, which you can use to
track user behavior that is normally difficult to track with traditional
web logging software. By tracking behavior, you can use Google Analytics
API to extract data and integrate it with data from your digital repository
to show granular data about individual items. Using this information,
digital libraries can learn how users use the site without extensive HCI
studies, and can use this information to improve the user experience.
The Martha Berry Digital Archive Project: A Case Study in Experimental
pEDagogy <http://journal.code4lib.org/articles/6823>

Stephanie A. Schlitz and Garrick S. Bodine

Using the Martha Berry Digital Archive Project as an exploratory case
study, this article discusses experimental methods in digital archive
development, describing how and why a small project team is leveraging
undergraduate student support, a participatory (crowdsourced) editing
model, and free and open source software to digitize and disseminate a
large documentary collection.
Using Semantic Web Technologies to Collaboratively Collect and Share
User-Generated Content in Order to Enrich the Presentation of Bibliographic
Records–Development of a Prototype Based on RDF, D2RQ, Jena, SPARQL and
WorldCat’s FRBRization Web Service<http://journal.code4lib.org/articles/6695>

Ragnhild Holgersen, Michael Preminger, David Massey

In this article we present a prototype of a semantic web-based framework
for collecting and sharing user-generated content (reviews, ratings, tags,
etc.) across different libraries in order to enrich the presentation of
bibliographic records. The user-generated data is remodeled into RDF,
utilizing established linked data ontologies. This is done in a
semi-automatic manner utilizing the Jena and the D2RQ-toolkits. For the
remodeling, a SPARQL-construct statement is tailored for each data source.
In the data source used in our prototype, user-generated content is linked
to the relevant books via their ISBN. By remodeling the data according to
the FRBR model, and expanding the RDF graph with data returned by
WorldCat’s FRBRization web service, we are able to greatly increase the
number of entry points to each book. We make the social content available
through a RESTful web service with ISBN as a parameter. The web service
returns a graph of all user-generated data registered to any edition of the
book in question in the RDF/XML format. Libraries using our framework would
thus be able to present relevant social content in association with
bibliographic records, even if they hold a different version of a book than
the one that was originally accessed by users. Finally, we connect our RDF
graph to the linked open data cloud through the use of Talis’
openlibrary.org SPARQL endpoint.
GLIMIR: Manifestation and Content Clustering within
WorldCat<http://journal.code4lib.org/articles/6812>

Janifer Gatenby, Richard O. Greene, W. Michael Oskins, Gail Thornburg

The GLIMIR project at OCLC clusters and assigns an identifier to WorldCat
records representing the same manifestation. These include parallel records
in different languages (e.g., a record with English descriptive notes and
subject headings and one for the same book with French equivalents). It
also clusters records that probably represent the same manifestation, but
which could not be safely merged by OCLC’s Duplicate Detection and
Resolution (DDR) program for various reasons. As the project progressed, it
became clear that it would also be useful to create content-based clusters
for groups of manifestations that are generally equivalent from the end
user perspective (e.g., the original print text with its microform, ebook
and reprint versions, but not new editions). Lessons from the GLIMIR
project have improved OCLC’s duplicate detection program through the
introduction of new matching techniques. GLIMIR has also had unexpected
benefits for OCLC’s FRBR algorithm by providing new methods for identifying
outliers thus enabling more records to be included in the correct work
cluster.
Case Study: Using Perl and CGI Scripts to Automate a Quality Control
Workflow for Scanned Congressional
Documents<http://journal.code4lib.org/articles/6731>

Doreva Belfiore

The Law Library Digitization Project of the Rutgers University School of
Law in Camden, New Jersey, developed a series of scripts in Perl and CGI
that take advantage of the open-source module PerlMagick to automatically
review the image quality of scanned government documents. By implementing
these procedures, Rutgers was able to save staff working hours for document
quality control by an estimated 25% percent from the previous manual-only
workflow. These scripts can be adapted by novice Perl and CGI programmers
to review and manipulate large numbers of text and image files using
commands available in PerlMagick and ImageMagick.
From the Catalog to the Book on the Shelf: Building a Mapping Application
for Vufind <http://journal.code4lib.org/articles/6924>

Kathleen Bauer, Michael Friscia, and Scott Matheson

At Yale University Library (YUL), recorded reference transactions revealed
that after finding a book in the catalog patrons had difficulty knowing how
to use the call number to find the book on the shelf. The Library created a
mobile service to help locate the call number in the library stacks. From
any call number of a book in Sterling Memorial Library at YUL, a map will
be displayed which highlights that call number’s general area on a floor in
the stacks. YUL introduced the mapping application in Yufind, a catalog in
place at Yale since 2008 which is based on Vufind.
