The spectacular growth in the produced volume of published scientific and technical information during the last years makes it difficult to discriminate and localize the information of greater quality. The parallel development of technologies for the fast handling of great volumes of single information has partially solved the problem of the access and use of the most advisable information. Health technology assessment tries to facilitate the decision making on the introduction, diffusion or use of health technologies, being based on the best evidences available. In order to improve the process of searching for evidences, needed in the process of health technology assessment, the Agency of Health Technology Assessment of the Institute of Salud Carlos III (AETS) made a compilation of information resources that can be useful for searching biomedical information in general. This article presents the above mentioned compilation along with the description of the process of elaboration and the criteria of selection applied.
