El Servicio de Obtención de documentos en las bibliotecas virtuales: Nuevas oportunidades en la gestión de Documentos=Conocimiento.

Virtual libraries are great managers of the knowledge. Document Delivery Services (DDS) facilitate the access to a part of the “explicit knowledge”. The electronic application of the new information´s technologies, formats and the consortial purchases of the collections, give new opportunities for their development. Recent, national and international Literature is reviewed to analyze the impact of the Virtual Libraries in the transformation of the DDS. The conclusion is that a redefinition of DDS is taking place, as part of the rationalization of collection development, the acquisition of electronic publications and retrospective digitalization

¿Que utilizan nuestros usuarios investigadores hospitalarios? Evaluación de la colección en cuatro bibliotecas hospitalarias basado en el análisis de citas bibliográficas de la producción científica de una especialidad médica

INTRODUCTION: The increase of the scientific production, the price of the journal subscriptions and the volume of the consortia puchases along the last years, has made unavoidable the optimization of the management of the collections. Libraries carry out a continuous evaluation of their collection in order to build a basic and strong one that satisfies the needs of the users, thus achieving a balance between utility, quality and price. As a complement to other usage evaluation methods, some libraries are using the analysis of bibliographical citations of the scientific production of their users-researchers. REVISION-OBJECTIVE-HYPOTHESIS: We carried out a complete bibliographical revision on the analysis of citations as a method for the evaluation of the usage of the collections. Then we established the hypothesis that it was a good indicator to know the relevancy of the collection. We evaluated the collection of four libraries. METHODOLOGY: We looked for the scientific production of the Service of Neurology in 2006 in the most important databases. We analyzed the citations and their distribution and frequency, their presence in our collections (both individual and that of the consortium), of the rest of Spain and of outside of Spain, as well as their correlation. RESULTS AND CONCLUSIONS: Our last 10-year collections, both individual and consortium, satisfy more than 77% of the bibliographical citations used in the scientific production of our users. The citation analysis can be an effective tool to evaluate our collections at the present time so much as the basic collections that we keep

Las fuerzas de la colección de publicaciones periodicas de cuatro bibliotecas hospitalarias: análisis del servicio de obtención de documentos

Strengths of the periodic publication collections of four hospital libraries: analysis of the Document Delivery Service. Absctract:The collection development has the main objective of satisfying the community needs by creating base and strengthened collections on the long range, which complement other resources outside the Library. Nowadays, electronic formats and consortial buying have made it easier to access to more information and services and have also homogenized the collections due to the unified buying of the serial packages. We have also assisted to dramatic changes in the users’ habits in the sense they look up an ever more abundant and multidisciplinary information, a fact that we can attribute, at least partially, to an easier access to the bibliographic funds, despite in some cases only as a bibliographic reference. To gather all the information the users demand we must make a strategic planning at least in two perspectives: the development of a basic good quality collection for our own users and also the development of an attractive and necessary collection for the whole libraries community. The general objective of the present study is to find out which are the strengths of our serial collections for external libraries, both in the sense of the titles and subjects that other libraries request and of the temporal period of reference. To achieve this, we have analyzed the document supply requests performed by external users in four hospital Libraries in Madrid (Spain). These data will give us information about the external strengths of our collections, both for our own consortium and for the other libraries. Knowing the strengths of our collections can help us to maintain a cost balance between the resources supplied and requested from our Library through the Document Delivery Service; besides, it can lead to a cost reduction due to the optimization of the utilization of the existing resources with satisfaction of a high proportion of the total demand. Policies for the development of library collections and of the Document Delivery Service should be coordinated in order to achieve a delicate balance between resources that can be acquired in property and those that can be easily and cheaply accessed. All the libraries included in the consortium must assume and implement these policies, both for the development of their own collections and for the interlibrary loans. This strategic policy can lead to an increase of the collections and also to an expansion of the interlibrary agreements that allow diversification of these collections

Pautas para la formulación de una política de gestión de la colección en bibliotecas de ciencias de la salud hospitalaria

The concept of collection has evolved throughout history due to the change in libraries´s mision and objetives. These changes produce a transformation in the philosophy of collection management as this is not only constructed to meet the needs of the hospital community (research, teaching and clinic), but also must be focused on the efficiency of its continued use. The collection management in the current Information Society encompasses all activities necessary to provide access to Health Sciences resources and information. The objetive is to establish the necessary guidelines for the development of a proper collection management policy or program for a hospital’s health sciences library in order to meet the current resources and contents needs of the library’s institutinal users in the Digital Age. The method is a comprehensive literature review and study of developed collection management policies and programs we established guidelines, that were subject to debate and discussion in the working group formed by four health science information professionals librarians. The results is the preparation of guidelines for the formulation of a collection management policy of the health science hospital library. This policy included as base: the guidelines formulated by the American Library Association in 1977, the division established by Clayton and Gordman in 2001 of two different statements within its structure in terms of management and collection development, and the standards necessary to adapt the objectives of the library, users, and the institution to the current requirements of digital content and resources. And the conclusions are that our collections and their management has changed and we need to adapt the collation management policies to the new requirements and targets. The collection management policy is the primary tool to build, guide and maintain appropriate and coherent collections, to sets the standart strategy to follow for the advancement of health science hospital libraries and their integration into the healthcare context

The impact of the electronic journals access on the inter-library loan of the hospital libraries: Analysis of four health sciences libraries

During the year 2003, the Health Sciences libraries of the Clínico San Carlos, La Paz, Móstoles and Ramón y Cajal Hospitals have participated in the consortial purchase of electronic journals that conform the electronic journal collection of the “Virtual Library Laín Entralgo”. Until 2002 the electronic format in our libraries was subordinated to those journals that gave away free electronic access with the paper subscription. Only Móstoles Hospital subscribed to ProQuest Medical Journal aggregator in 2002. OBJECTIVE To analyse the impact of the access to the electronic journals on the interlibrary loan of the four health sciences libraries, comparing the results of the different years and their relation to the consortial libraries. METHODS We have analysed the specific characteristics of each library in terms of volume and antiquity of collection, total volume of interlibrary loans and the loan volume between the consortial libraries, all these in values of requests and deliveries in the last three years. RESULTS Due to the consortial purchase, the libraries’ collections have shown an important increase in size, greater in those libraries with smaller initital collections. The total number of deliveries and requests of documents has decreased, this reduction being more significant between the years 2001 and 2002, and milder with tendency to stabilize in the year 2003. Of the total volume of the Interlibrary loan, more than 73% (2001) is effected within the libraries in the consortium and during these years it has also decreased mildly (62% in 2002 and 60% in 2003). The smaller the library collection, the more requests are made to the consortial libraries and the bigger the library collection, the more deliveries are effected. CONCLUSION During the last three years, our interlibrary loan borrowing volume has decreased, the reduction having seen stronger in 2002 than in 2003. This result is due to some consortial libraries subscribing to electronic journals aggregator in 2001, to the impact of free access to electronic journals through promotional access and the access through unconventional (pirate) methods to electronic journals. In 2003, the interlibrary loan decreased in the consortial libraries due to shared electronic collection
