As you all know…2005 materials can be received as early as Autumn of 2004, or as late as yesterday. The JCR considers all materials with a publication year of 2005, processed from any point in 2004 on forward to any materials indexed in time for the JCR extraction. For the past 2 years, we have used an extraction close date of March 1. Generally, then, it means that JCR 2005 will include materials received as late as the second or third week in February. 1.7 million articles processed in 2005 – references from these articles to previously published material Nearly 35 million cited references processed Citas Artículos fuente – publicados en 2010 Referencias Citadas – publicadas en 2010 Referencias citadas – publicadas en 2008 o 2009 2

8 HISTORIA DE: Web of Science®
Web of Science: v v v5 v6 v7 Science Citation Index Arts & Humanities Citation Index Thomson Scientific - A culture of innovation with an emphasis on our customers 1961 Science Citation Index launched - In 1955, Dr. Eugene Garfield revolutionized scientific research with his concept of citation indexing and searching. Science Citation Index® (SCI) was launched in 1961 which included 562 journals and 2 million citations. 1966 Dialog online information retrieval system is operational long before the commonplace use of the Internet. 1972 Dialog offers the first publicly available online research service. A company is born. MDC Founded and original mainframe/time-share IP management systems PatentMaster (Patents) and MarkMaster (Trademarks) launched. First ever patent payment service introduced. 1974 World Patents Index - In 1948 Monty Hyams would make frequent visits to the British Patent Office and identifying passages of particular interest in chemical patents. The line numbers were passed on to his father, who transcribed the passages in neat longhand. In 1974 his company Derwent provides complete coverage of patents from all technologies through launch of World Patents Index 1976 Derwent is one of the first organisations to go online with the first online implementation of WPI on the host SDS-ORBIT. 1989 MicroPatent is founded in 1989 in response to the needs of patent professionals who required electronic data in CD-ROM format. This is at a time when hard-copy documents were the norm. 1990 Derwent launches GENESEQ, the first database of sequences from patents, delivered in a format that runs on new sequence analysis software   1995 IDRAC global regulatory intelligence database is launched with 15 country modules. It is a CD-ROM product and the first of its kind. 1996 Techstreet (then called CSSINFO) launches first-ever web site for searching and ordering industry codes and standards online. 1997 ISI launches Web of Science providing seamless access to current and retrospective multidisciplinary information from approximately 8,700 of the most prestigious, high impact research journals in the world. The product is a breakthrough listing both the cited and citing works that allows researchers to move back in time to locate previously published papers but uniquely allowing you to move forward in time--to determine who has subsequently cited an earlier work. The database covers virtually all disciplines whereas traditional services are limited to a single field. 1998 MicroPatent becomes the first company in the world to provide PCT full text electronically. Similarly, the Company is the first to have US full text data back to 1836 and the first with published Great Britain applications back to 1916, among many others. 2000 Delphion is launched using IBM's existing Intellectual Property Network and uses it as the foundation for its marketplace, enables businesses to search, analyze, buy, sell and license millions of patents across different industries. Techstreet launches first-ever searchable database of industry standards and technical books combined. 2001 ISI develops ISI Web of KnowledgeSM - the single, sophisticated platform that unites journal literature, patents, chemical compounds, and genetic sequencing, and integrates proceedings and additional print and electronic sources. Newport Horizon, a Web-based strategic intelligence system for generic and speciality pharma is released 2004 Thomson Pharma is launched - A dynamic information solution for the pharmaceutical and biotechnology industries. It is a single solution that professionals working at all stages of drug development can personalize to suit their needs. 2005 Century of Science makes hundreds of thousands of older, twentieth century scientific journal items available in one place and on one platform for the first time.

10 ¿Qué es el Índice H? El índice h es un sistema propuesto por Jorge Hirsch, de la Universidad de California, para la medición de la calidad profesional de físicos y de otros científicos, en función de la cantidad de citas que han recibido sus artículos científicos. Un científico tiene índice h si ha publicado h trabajos con al menos h citas cada uno. 10

16 EL VALOR DE UNA CITA ¿Por qué las personas citan?
Para dar crédito a los pioneros Identificar una metodología Mostrar información de respaldo Autenticación de Información, reproducción de trabajos, etc. Correcciones Critica / Opinión Las citas son un indicador del impacto de un artículo para la comunidad científica. El valor de una cita es solo tan importante como su misma fuente. Claramente una cita que proviene de una prestigiosa revista tiene más valor que una cita que proviene de una fuente desconocida. Cómo podemos estar seguros de que la fuente de la cual proviene la cita es confiable? “When to Cite”, E. Garfield, Library Quarterly, v66, p , 1996

18 Un pequeño número de revistas publican la mayor cantidad resultados científicos impactantes.
Solamente 3,000 revistas cubren el 80% de los documentos más importantes… .. y estas mismas cubren el 92% de lo que es citado. Por qué ser selectivo? Dr. Eugene Garfiel, presidente y fundador de Thomson Scientific, comprendió que un pequeño número de revistas publican la mayor cantidad de documentos citados…. 2003 Journal Citation Reports lists 7,621 journals etc.. Clearly the bulk of published and cited articles is concentrated in a relatively small number of journals. Core is not static – add and delete journals throughout the year. Editors: information professionals, librarians, graduate degrees in science Experts in the literature of their subject. They see every new journal… 7,621 journals publicaron 814,967 artículos que recibieron 20,834,641 de citas 4% de journals (300) publicaron 30% de artículos (239,206) 4% de journals (300) recibieron 51% de las citas (10,681,596)
