library/mobile: Tips on Designing and Developing Mobile Web Sites

Kim Griggs, Laurie M. Bridges, Hannah Gascho Rempel — Mon, 23 Nov 2009 18:15:57 +0000

Mobile applications can support learning by making library resources more ubiquitous, by bringing new users to the library through increased accessibility to the resources libraries offer, and by creating a new way to enhance connections between patrons and libraries. This increased use of mobile phones provides an untapped resource for delivering library resources to patrons. The mobile Web is the next step for libraries in providing universal access to resources and information. This article will share Oregon State University (OSU) Libraries’ experience creating a mobile Web presence and will provide key design and development strategies for building mobile Web sites.

Automated Metadata Formatting for Cornell’s Print-on-Demand Books

Dianne Dietrich — Mon, 23 Nov 2009 18:15:56 +0000

Cornell University Library has made Print-On Demand (POD) books available for many of its digitized out-of-copyright books. The printer must be supplied with metadata from the MARC bibliographic record in order to produce book covers. Although the names of authors are present in MARC records, they are given in an inverted order suitable for alphabetical filing rather than the natural order that is desirable for book covers. This article discusses a process for parsing and manipulating the MARC author strings to identify their various component parts and to create natural order strings. In particular, the article focuses on processing non-name information in author strings, such as titles that were commonly used in older works, e.g., baron or earl, and suffixes appended to names, e.g., "of Bolsena." Relevant patterns are identified and a Python script is used to manipulate the author name strings.

Ead McTaggart: Using VBA to Automate EAD Container List Tagging

Randall Miles — Mon, 23 Nov 2009 18:15:55 +0000

Faced with the prospect of converting 200-page container lists to Encoded Archival Description (EAD), the author programmed a Microsoft Access® database using Visual Basic for Applications (VBA) to automatically insert the necessary EAD tags and their attributes. Some work is still required to ensure that the container list is properly formatted before importing into the database. Once formatted, the database, named Ead McTaggart, will convert a 7,000 line Microsoft Excel® container list, where each line represents a series, sub-series, or folder title, into a properly tagged EAD container list in about five minutes. As written, Ead McTaggart will handle up to six component levels, but can be modified to handle more. Although many institutions use Archivists' Toolkit or Archon for this functionality, many libraries and archives who have not implemented those tools will find that EAD McTaggert minimizes the work of converting existing container lists to EAD finding aids with a low time investment for implementation.

Automatic Preparation of ETD Material from the Internet Archive for the DSpace Repository Platform

Tim Ribaric — Mon, 23 Nov 2009 18:15:54 +0000

A big challenge associated with getting an institutional repository off the ground is getting content into it. This article will look at how to use digitization services at the Internet Archive alongside software utilities that the author developed to automate the harvesting of scanned dissertations and associated Dublin Core XML files to create an ETD Portal using the DSpace platform. The end result is a metadata-rich, full-text collection of theses that can be constructed for little out of pocket cost.

How Hard Can It Be? : Developing in Open Source

Joann Ransom with Chris Cormack and Rosalie Blake — Fri, 26 Jun 2009 17:22:58 +0000

In 2000 a small public library system in New Zealand developed and released Koha, the world’s first open source library management system. This is the story of how that came to pass and why, and of the lessons learnt in their first foray into developing in open source.

Extracting User Interaction Information from the Transaction Logs of a Faceted Navigation OPAC

Cory Lown and Brad Hemminger — Fri, 26 Jun 2009 17:22:57 +0000

This paper discusses the analysis of Apache web server logs from a faceted catalog interface (OPAC) at North Carolina State University. By grouping individual HTTP requests into user sessions and analyzing in that context, requests can be understood as particular user actions, with more specificity as to purpose and effect of an action. Client IP address and time are used as a sufficient proxy for determining user sessions from logs. Some initial exploratory findings of user behavior in the NCSU OPAC are provided, including that users make use of facets less than of text searching, and that some facet groups are used significantly more than others. Links are provided to the scripts used to make this session-based analysis, which could be modified for use with other facetted OPACs which use an Apache front-end.

Using a Web Services Architecture with Me, Myself and I

Stephen Meyer — Fri, 26 Jun 2009 17:22:56 +0000

The UW-Madison Libraries Library Course Page system is used to deliver electronic reserves materials and course-focused library instruction webpages to students. As part of a rewrite of our system we broke the application into three component pieces: a file repository, a course timetable data service, and an interface application for building and viewing individual course pages. The new three-piece system was written with an inward facing service-oriented architecture that allowed us to choose the best technologies to solve each of the tasks the entire system needs to accomplish.

Deciphering Journal Abbreviations with JAbbr

Keith Jenkins — Fri, 26 Jun 2009 17:22:55 +0000

JAbbr is an online tool developed at Cornell University to help users decipher journal title abbreviations. This article discusses why these abbreviations are so problematic, and how traditional tools are often insufficient, and then describes the novel approach used by JAbbr. Given an abbreviation, JAbbr creates a regular expression for fuzzy matching, tests it against a list of serial titles extracted from the library catalog, and returns a list of possible matches to the user. JAbbr is available as a web site and as a web service.

Christine Schwartz — Mon, 30 Mar 2009 22:30:59 +0000

The intelligent use of technology in libraries continues to be one of our most crucial challenges. For those of us who became librarians because we loved to explore the book stacks, we are now finding new ways to explore both old and new content in digital form. With issue 6 of the Code4Lib Journal we hope you will find new ways to explore, experiment, and bring to your library users what they want and need.

Using OAI-ORE to Transform Digital Repositories into Interoperable Storage and Services Applications

Mon, 30 Mar 2009 22:30:58 +0000

In the digital age libraries are required to manage large numbers of diverse objects. One advantage of digital objects over fixed physical objects is the flexibility of 'binding' them into publications or other useful aggregated intellectual entities while retaining the ability to reuse them independently in other contexts. An emerging framework for managing flexible aggregations of digital objects is provided by the Open Archives Initiative (OAI) with its work on Object Reuse and Exchange (ORE). This paper will show how OAI-ORE is being used to manage content in digital repositories, in particular institutional repositories, and has the potential ultimately to transform the conception of digital repositories.

Semi-automatic Citation Correction with Lemon8-XML

MJ Suhonos — Mon, 30 Mar 2009 22:30:57 +0000

The Lemon8-XML software application, developed by the Public Knowledge Project (PKP), provides an open-source, computer-assisted interface for reliable citation structuring and validation. Lemon8-XML combines citation parsing algorithms with freely-available online indexes such as PubMed, WorldCat, and OAIster. Fully-automated markup of entire bibliographies may be a genuine possibility using this approach. Automated markup of citations would increase bibliographic accuracy while reducing copyediting demands.

Visualizing Media Archives: A Case Study

Chris Beer, Courtney Michael, and Mayo Todorovic — Mon, 30 Mar 2009 22:30:54 +0000

The WGBH Media Library and Archives is piloting an online media archive for scholarly research. In conversation with users, we have discovered they want to quickly pinpoint items relevant to their work and get an overview of collections and their relationships to other materials. To demonstrate the size and complexity of our collection to users in a meaningful way, WGBH is employing data visualization techniques to provide an interactive, graphical representation of the various relationships between items. This article discusses the techniques employed in implementing our relationship map, emphasizes the cataloging techniques required for this effort, and offers code and examples to spark discussion about ways to improve or extend this effort.

Course Views: A Scalable Approach to Providing Course-Based Access to Library Resources

Jason Casden, Kim Duckett, Tito Sierra and Joseph Ryan — Mon, 30 Mar 2009 22:30:53 +0000

The NCSU Libraries’ Course Views project, along with a locally developed widget web service, improves course-based access to library collections and services by dynamically generating library course pages for all 6000+ courses at NCSU. By automatically generating custom content when possible and showcasing authored content when available, Course Views is able to achieve full course coverage without significantly increasing staff time to create and manage content. This paper will describe the system and the use of web services to achieve scalable and sustainable delivery of course-related library content.

Integrating Process Management with Archival Management Systems: Lessons Learned

J. Gordon Daines, III and Cory L. Nimer — Mon, 30 Mar 2009 22:30:52 +0000

The Integrated Digital Special Collections (INDI) system is a prototype of a database-driven, Web application designed to automate and manage archival workflow for large institutions and consortia. This article discusses the how the INDI project enabled the successful implementation of a process to manage large technology projects in the Harold B. Lee Library at Brigham Young University. It highlights how the scope of these technology projects is set and how the major deliverables for each project are defined. The article also talks about how the INDI system followed the process and still failed to be completed. It examines why the process itself is successful and why the INDI project failed. It further underscores the importance of process management in archival management systems.

How to Build an XML Web Client for the Gold Rush Link Resolver’s XML Gateway Web Services Layer

Brian Kysela — Mon, 30 Mar 2009 22:30:51 +0000

The Gold Rush link resolver (GRLR) is part of a suite of programs developed by the Colorado Alliance of Research Libraries (CARL) which help manage a library's electronic resources. It contains the essential features required to perform link resolution, and comes at a substantial discount compared to other commercial Link Resolvers. After a comprehensive review of the available options, the library at the University of Tennessee at Chattanooga (UTC) chose to implement Gold Rush over the summer of 2008. The UTC library also decided to take advantage of the release of the Gold Rush XML Gateway Web Services Layer by the Colorado Alliance in the spring of 2008. This article is a case study of how the UTC XML Web client was built and the steps necessary to successfully deploy such a client.

‡biblios: An Open Source Cataloging Editor

Chris Catalfo — Mon, 15 Dec 2008 19:11:44 +0000

‡biblios is an open source cataloging editor designed to allow libraries to perform copy and original cataloging in a web based environment. ‡biblios allows users to search for, edit, and save bibliographic records in the MARC21/MARCXML formats. It also allows users to send records directly to integrated library systems such as the Koha ILS. Where most MARC editors are part of an integrated library system (and therefore require logging in), ‡biblios allows users to catalog with an open source standalone system available anywhere via a web browser. Unlike other cataloging editors, it offers an attractive user interface for searching, saving and editing cataloging records. This article describes the system architecture and design of ‡biblios.

User-Centred Design and Agile Development: Rebuilding the Swedish National Union Catalogue

Henrik Lindström and Martin Malmsten — Thu, 01 Jan 1970 00:00:00 +0000

With a new generation of OPACs emerging that attempt to address longstanding shortcomings, how do we make sure that we do not lose ground again in the future? This article suggests a combination of iterative development and user-centred design as a way to develop systems that will meet the constantly changing expectations of users by providing both functionality and usability. It gives a short introduction to iterative software development and user-centred design. A case study of the development of the new version of LIBRIS (http://libris.kb.se), the Swedish National Union Catalogue, is used as an example of how these methodologies can benefit from each other in practice.

Affinity Strings: Enterprise Data for Resource Recommendations

Cody Hanson, Shane Nackerud, and Kristi Jensen — Mon, 15 Dec 2008 19:11:14 +0000

The University of Minnesota Libraries have created a MyLibrary portal, with databases and e-journals targeted to users, based on their affiliations. The University's enterprise authentication system provides an "affinity string", now used to personalize the MyLibrary portal. This affinity string automates discovery of a user's relationship to the University--describing a user’s academic department and degree program or position at the University. Affinity strings also provide the Libraries with an anonymized view of resource usage, allowing data collection that respects users' privacy and lays the groundwork for automated recommendation of relevant resources based on the practices and habits of their peers.
