OPAC 2.0

El concepto de OPAC 2.0 ha sido ya estudiado con anterioridad (Breeding, 2007; Casey, 2007; Margaix-Arnal, 2007, Maniega, 2008; Macias, 2008) y se puede entender como la aplicación de las tecnologías y las actitudes de la Web 2.0 al catálogo bibliográfico. En primer lugar las tecnologías 2.0 son una más de las piezas que ayudan a mejorar la experiencia del usuario (junto a otras como la Usabilidad, la Arquitectura de la Información, etc.). En segundo lugar si sus datos son más abiertos el OPAC puede posicionarse mejor entre las herramientas de recuperación de información utilizadas por los usuarios. En tercer lugar el uso de información social y el aprovechamiento de la inteligencia colectiva ayudarán a reforzar el papel del OPAC como una herramienta de descubrimiento de información y no sólo como localizador de documentos ya conocidos. Ahora bien, para que el usuario aporte información al sistema es necesario el cuarto objetivo: que el OPAC sea una herramienta útil y que la información que aporte el usuario revierta en un beneficio directo para sus propios objetivos.

This article presents information on OCLC 2.0, a kind of cataloging code. It is sometimes referred to as the Next Generation Catalog, OPAC 2.0 and Dis-Integrated Library System. OCLC has been promoting a new WorldCat Local service, which leverages the metadata and data-mining capabilities of WorldCat while customizing the interface with local branding and search parameters. Because of the growing number of contributing libraries and its absorption of the RLG Union Catalog, the WorldCat database has grown in size to 85 million bibliographic records.

  A study conducted at the University of Illinois at Urbana-Champaign (UIUC) Library examines data from unfilled ILL requests to determine the status of materials housed in the Main Bookstacks of the library's collection. The study focuses on ILL requests that were not filled due to material missing from the collection. Results of the study identified training issues with staff and student employees, indicated that high use materials were more subject to loss, recognized that overcrowding of the collection contributed to error, and noted that maintenance shifting of materials created additional problems for locating materials. Analysis of the data resulted in a suggested procedure to use unfilled ILL requests to update the library's OPAC for more accurate representation of the status of materials in the collection.

Web 2.0 has raised new expectations from the library users : after reading a book, they wish to rate it, provide some comments or review about it and tag it for themselves or for others. They also expect to discover other interesting books thanks to the contribution of other people. Those functions, summarized under OPAC 2.0, are now provided by several Integrated Library Systems (ILS), at least partially. But, due to the slow development of some products, other paths were also explored: Content Management Systems (CMS) or specific software. CMS does provide the required functionalities like tagging and commenting. Some pioneers thus decided to develop a new Web OPAC based on CMS. Another approach was to build an OPAC that is independent from any ILS and which offers the required functionalities. In this paper, we propose to review the options available for the librarians wishing to offer Web 2.0 functionalities to their users. We also provide a synthesis of our own experience in implementing an OPAC 2.0 into our Library.

In my previous column I presented some past views of the future of the library and the library catalog. Writing on the threshold of the computer revolution, most of those futurists correctly foresaw a library and catalog that could be accessed from the user’s office or home. Some even predicted the eventual dissolution of the physical library, with all documents and all services being digital. But none of them envisioned the rise of a vibrant information environment entirely outside of libraries: the World Wide Web. Our users have shifted their attention from the library to other sources of  information. The question today is not how do we get users into the library, but how can we take the library to the users. The answer will necessarily involve a transformation of the library catalog.

In this paper, a prototype of an Online Public Access Catalog (OPAC) is presented. This new OPAC features new functionalities and utilizes web 2.0 technologies in order to deliver improved search and retrieval services. Some of these new services include social tag annotations, user opinions and ranks and tag-based similarity searches. The prototype is evaluated by a user group through questionnaires, interviews and with the system's integrated logging mechanism. The results are encouraging enough and show that Library 2.0 technologies seem to be acceptable by the majority of the users.

John, H. "The VuFind implementation at Villanova University." Library Hi Tech vol. 27, n. 1 (2009).  pp. 93-105. http://www.emeraldinsight.com/10.1108/07378830910942955
Purpose – This case study seeks to document the experiences of Villanova University's Falvey Library staff as they developed and implemented the VuFind open source discovery tool for libraries. It aims to address the decision to hire a programmer for the library, the decision to make the VuFind software open source, and the library's development and implementation processes. Design/methodology/approach – The author interviewed, recorded, and corresponded with members of the library staff on multiple occasions over a five-month period during the ramp-up to, and just after, the launch of the new software. The paper is complemented by three podcasts created from the interview material that are available online. Findings – The creators of VuFind took a relatively informal approach to library software development. However, the resulting software has been well received, both by the library development community and Villanova University. Keys to this success were close attention to user expectations deriving from their experiences using widely available web-based search tools and applications, a continuous process of sharing work and soliciting input, and rapid improvements to the software. The open source development process facilitated the sharing and collaboration that made this rapid improvement possible. Practical implications – Other libraries that are considering the possibility of developing their own software may find Villanova's experience and approach useful in determining where to focus their planning and concentrate their resources. Originality/value – The case study will be of interest to persons engaging in or considering whether to engage in open source development of a library application. It will also appeal to library administrators interested in learning about the technology planning or software development.

Lim, L. "LINC+: Our leap towards a Web 2.0 OPAC interface." National University of Singapore vol., n. (2008).  pp.: http://www.las.org.sg/pa_ly.pdf
As internet search engines compete with online library catalogues as the source of information, the NUS Libraries faces the ultimate challenge of being the preferred gateway for finding information. We respond to this by providing user-centred information services and have begun our journey of revitalising our OPAC to make materials more easily accessible to our users. We leap from a Web 1.0 LINC (Library Integrated Catalogue) towards a Web 2.0 OPAC by offering a new menu of features to delight the millennial generation of users. Encore is our new discovery services platform which offers Web 2.0 features such as faceted search and tagging. The new Popular Choices feature suggests items based on circulation and community popularity while Patron Ratings and Community Reviews provide yet another channel of discovery for the user. Encore promises to transform the user experience by going beyond the conventional online library catalogue and strategises the quest for information in a single search interface.

Maness, J. M. "Library 2.0 theory: Web 2.0 and its implications for libraries." Webology vol. 3, n. 2 (2006).  pp. 2006. http://www.webology.ir/2006/v3n2/a25.html?q=link:webology.ir/
This article posits a definition and theory for "Library 2.0". It suggests that recent thinking describing the changing Web as "Web 2.0" will have substantial implications for libraries, and recognizes that while these implications keep very close to the history and mission of libraries, they still necessitate a new paradigm for librarianship. The paper applies the theory and definition to the practice of librarianship, specifically addressing how Web 2.0 technologies such as synchronous messaging and streaming media, blogs, wikis, social networks, tagging, RSS feeds, and mashups might intimate changes in how libraries provide access to their collections and user support for that access

El opac ha estado en el ojo del huracán durante bastantes años, evolucionando para dotar a los programas gestores de más funcionalidades pensando en la accesibilidad, entendida como la capacidad de recuperar la información. Es lógico imaginar que esto ha sido en pro del usuario; pero si lo analizamos con detenimiento veremos que los opacs tienen bastantes deficiencias en ese sentido. Hay que dejar que realmente se abran al usuario, que sean auténticas herramientas vertebradoras del acceso a la información, bibliográfica o no, donde el usuario participe de su crecimiento y enriquecimiento. En este artículo se abordan algunos de los puntos débiles presentes en la gran mayoría de catálogos, ofreciendo algunas pistas para la intersección entre los procesos de innovación tecnológica que se puedan aplicar y, la participación social al amparo de la tan conocida hoy en día Web 2.0

  In this article are compared traditional OPAC systems, enriched OPAC, social OPAC and social cataloguing systems. The aim is to underline new theoretical trends and to offer a taxonomic outline of such tools, according to the interaction level granted to users and to the chance to manage user’s generated contents from the point of view of the application of Web 2.0 tendencies to libraries, in the Library 2.0. At the end, a brief review of softwares, open source and not, that seem promising for this future application.

Desde que la web 2.0 tomó las portadas de los semanarios más importantes del mundo se ha convertido en un tema, más que de moda, inevitable. Se ha estudiado la Web 2.0 desde múltiples perspectivas y ha sido objeto de estudio en las más diversas áreas del conocimiento. El objetivo de este trabajo es identificar las funcionalidades 2.0 y ver cómo están afectando o pueden afectar al producto clave de cualquier biblioteca: su OPAC. Se analizan cuáles han sido los cambios más relevantes de los OPAC desde su aparición, cómo está influyendo la Web 2.0 analizando algunos ejemplos. En la parte final del trabajo se propone un modelo de aplicación de estas tecnologías a un catálogo bibliográfico.

El fomento de la lectura entre los universitarios es una de las nuevas funciones que las bibliotecas Universitarias están asumiendo como propias. La Universidad actual ya no se concibe como un mero centro de investigación y capacitación profesional. Sin perder de vista estas funciones nucleares, actualmente buscan una formación integral de la persona, rescatando valores humanistas olvidados durante tanto tiempo.

Purpose – The purpose of this paper is to present the implementation of LibraryThing for Libraries (LTFL) in an academic library and analysis of usage of LTFL data and their potential for resource discovery in the catalog. Design/methodology/approach – The paper reviews the literature on social tagging and incorporation of third-party user-generated metadata into the library catalog. It provides an assessment based on the analysis of total absolute usage figures and frequency of use of LTFL data. Findings – Based on the data available, usage of LTFL data in the catalog is low, but several possible contributing factors are identified. Originality/value – The paper contributes to the literature on the implementation of LTFL in an academic library and provides usage statistics on LTFL data. It also provides directions for future research about tagging in the catalog.

Purpose – Access to library collections in an era where users want to “get” rather than “find” offers particular challenges. This paper seeks to explore users' needs for bibliographic records in a primarily full text environment. Design/methodology/approach – The paper describes the need for access to parliamentary and library information from the Australian Parliament and its use by Senators and Members. It then outlines the approach taken to develop and implement a new search system, ParlInfo, which applied a repository and search system that provides integrated access to bibliographic and full text information. Launched in September 2008, it offers facets, alerts, RSS feeds and other Web 2.0 functionality to both the Australian public and Parliamentary Network users accessing library collections and parliamentary collections. Findings – The paper offers insights into solutions which meet the information needs of Senators and Members and the public; and the application of library/web 2.0 solutions. It is relevant to organisations seeking to offer a single gateway to their collections. Research limitations/implications – The paper offers an approach based on understanding the whole needs of users, rather than applying a traditional assumption that resource discovery should be based only on catalogue records through an OPAC. Practical implications – The paper provides a model based on integrated access to resource through metadata, full text “crawled” from web sites and full text resources, such as Hansards, that can be applied in many organisations. Originality/value – The paper's value is in thinking about how the catalogue can be “turned inside out” for the twenty-first century users' needs.

Recommender systems are useful tools for adding a reference component to a library catalog, and they help develop library catalogs that serve as customer-oriented portals, deploying Web 2.0 technology. Recommender systems are based on statistical models, and they can lead users from one record to similar literature held in the catalog. In this article we describe the recommender system BibTip, developed in Karlsruhe University, and we discuss its application in libraries.

El OPAC ( On Line Public Access Catalog ) de una biblioteca es una herramienta esencial para los usuarios. En los últimos años, con el auge de las tecnologías participativas que son herramientas surgidas por el uso de la web social, se ha pensado en utilizarlas y aplicarlas a las bibliotecas para comunicarse, formar e informar , integrar al usuario en los servicios. Como consecuencia aparece el OPAC 2.0 u OPAC social: la transformación del rígido catálogo tradicional en uno más familiar para el usuario, un catálogo que aprovecha las ventajas que ofrece la web. El nuevo cambio, es la implementación de las tecnologías 2.0 permitiendo una mayor reutilización de sus contenidos y la participación de los usuarios.Este concepto ha sido estudiado con anterioridad por muchos autores y se puede entender como la aplicación de las tecnologías y las actitudes de la web 2.0 al catálogo bibliográfico. Es importante justificar la necesidad de este tipo de aplicaciones e identificar qué puede aportar la web a los OPAC.En este trabajo se realiza una reflexión acerca de lo que hoy debería ser el catálogo en línea de una biblioteca y no lo que realmente es en la mayoría de los casos: una caja de búsqueda con algunas posibilidades hipertextuales cuya filosofía está basada en una tradición bibliotecaria básicamente conservadora. La evolución de los OPACs se quedó estancada con la aparición de la Web e incluso sufrió un fuerte retroceso respecto a los sistemas existentes a comienzos de los 90. Sorprendentemente no se ha hecho casi nada en cuanto a su diseño aún a pesar de la extraordinaria evolución sufrida en la World Wide Web desde 1995. Una vez revisadas las propuestas actuales y los modelos existentes y en base a la bibliografía, se analizarán las funcionalidades deseables de un OPAC 2.0.

The most recent transformations of online catalogues are described with specific examples given: the new generation catalogue at North Carolina State University and the work being carried out by the library service of the University of California to redefine the structure of services offered through their catalogue. The main features of the current Web 2.0 are described and how it is applied to Library 2.0 as a background for these transformations. All of these changes represent a (Revolution in the sense that users are considered the central and primary objective of the services and resources offered by the library. (Author abstract)

North Carolina State University has developed an Application Programming Interface (API) “platform”, called CatalogWS, to provide web service access to catalog search and availability services. This project was motivated by the realization that the discovery of library collections should not be limited to a single catalog application, and such a platform could support the efficient creation of novel interfaces based on consistent services. Some technical discussion of the CatalogWS architecture is provided, including a technical description of web service protocols implemented. Several applications providing discovery in novel contexts have already been developed based on CatalogWS, and are described in some depth. CatalogWS has helped create a culture of experimentation and enabled a larger group of staff to work with library catalog data and services in new and interesting ways.

The need to develop new OPACs that meet the needs of users better is becoming well acknowledged. How libraries can transform their OPACs to modern web friendly formats is not yet clear. This paper describes the State Library of Tasmania’s experience in developing a new OPAC by exporting bibliographic data to a software package outside the ILMS. Issues involved with the provision of a user-oriented, browsable, or facet-driven interface are described, the two most important ones for libraries being how to change cataloguing processes so as to deliver the required data and search functionality, and how to share evaluative and usage data about our resources.

Purpose – This paper aims to examine the social phenomenon known as tagging and its use in libraries' online catalogs, discussing folksonomies, social bookmarking, and tagging web sites. The paper also seeks to weigh the advantages and disadvantages of a controlled vocabulary such as the Library of Congress Subject Headings, and how tagging can assist the LCSH in information retrieval. LibraryThing and the University of Pennsylvania's PennTags are examined. Design/methodology/approach – Review of recent literature in print and online, as well as browsing Library OPACs using tagging, was the basis for the paper. Findings – The paper concludes that access to information is the main purpose of cataloging, and use of both traditional methods of cataloging as well as interactive methods such as tagging is a valid method for reaching library users of the future. Originality/value – The paper lists many problems and concerns of which to be aware, if a library should choose to adopt tagging for their catalog. It looks at the options of using outside web sites to provide the tags as well as creating tagging systems on the library's web site itself. The focus of the paper is how libraries can use tagging, as opposed to the phenomenon of tagging itself, as well as a discussion of how tagging compares with controlled vocabularies.

Wenn man den Thesen von Tim O'Reilly1 folgt, ist „Web 2.0“ nicht nur eine Marketingworthülse oder eine Ansammlung von verschiedenen Internet-Technologien. Sicher gibt es Technologien und Strategien, die als Web 2.0-spezifisch gelten, wie die Modularität der Software, offene Schnittstellen, Rekombinierbarkeit der verschieden Anwendungen, kontinuierliche Veränderung („perpetual beta“), RSS/Atom, AJAX etc. Darüber hinaus umfasst der Begriff aber auch eine sehr starke soziale Komponente: Die Integration und Partizipation der NutzerInnen. Sie sind zugleich ProduzentInnen und NutznießerInnen der Inhalte und Strukturen, auf denen das Web 2.0 im Wesentlichen beruht. Dahinter steckt der Gedanke eines demokratischen „Mitmach-Webs“ voller emanzipierter NutzerInnen, die mit Freude und Engagement gestalten, erfinden und kommunizieren.

Purpose – The purpose of this paper is to introduce Commercial Mobile Video Service Trial (TOEST) of Korea Telecom (KT), relaying experience related to the implementation of mobile video service for portable devices to libraries and information management organizations that are interested in this service. Design/methodology/approach – Research data used were collected from internal materials such as unpublished project reports, RFI, RFP, etc. written throughout the process of implementing projects. The information also draws on the author's experience and involvement in TOEST trial between 2005 and 2007. Findings – From the technical perspective, it was confirmed that technical advancements and environments that enable the implementation of mobile video service for portable devices have been fully established. The technical areas that need to be further improved are the advancements of battery capacity, low-power consumption technology, and functional improvement of the I/O slot in portable devices. Research limitations/implications – TOEST provides only download type service for portable devices such as PDAs and PMPs. Streaming type service for mobile phones has been performed only for the purpose of internal tests. Practical implications – For information management organizations and libraries, mobile video service for portable devices is cutting-edge technical service that can provide new customer value to users. Also, it is possible to apply profit models from the commercial point of view. Originality/value – The paper introduces various technical and environmental elements as specifically as possible, including practical things that we have experienced during the course of implementing mobile video service systems for portable devices. Experience in TOEST development would be helpful to information management organizations and libraries planning to provide mobile video service for portable devices.

Durante esta última década las bibliotecas, los CRAIs - y en general servicios de información documentales- han realizado un enorme esfuerzo para poder ocupar un papel destacado en la sociedad. Éstos, como organizaciones que gestionan información, han tenido que integrar en sus sistemas los cambios tecnológicos necesarios para adaptarse a los nuevos retos. Para ello han realizado importantes inversiones tanto en tecnología pues era necesario actualizar la infraestructura, como en formación de su personal. La actual presencia de los servicios de información documentales en la Web es importante y además está en constante evolución, al igual que la Web.

In today’s fast moving world of technology, we can be sure that things will change, but we can’t predict the next biggest development. Web 2.0 started as a brainstorming conference on new web applications emerging from the ashes of the Internet dot.com collapse in 20011. Web 2.0 includes concepts such as social networking and participation on the Internet, user community involvement and tagging, blogs, wikis and syndicated feeds or alerts. Some of the best known Web 2.0 sites offer a public space to record and categorise data and images using folksonomy tagging for subject keywording. At Flickr (http://flickr.com) you can store, tag, share and retrieve your photo images online, in Del.icio.us (http://del.icio.us) tag your bookmarked web sites, and on Library Thing ( http://librarything.com), catalogue books to keep track of what you’ve read. Amazon.com fine tuned the incorporation of user feedback and engagement into search results and online shopping. Google has turned around user expectations of search and discovery, while challenging the role of libraries in providing access to information with its digitization program.

Vivam as bibliotecas vivas!
