Purpose-The importance of online public access catalogues (OPACs) has changed in recent years, mainly due to the large number of electronic resources now available. The aim of this study is to learn about and evaluate the use made by researchers of the OPAC of the library network of the Spanish Council for Scientific Research, the largest research institution in Spain. Design/methodology/approach-To this end a questionnaire was drafted with questions pertaining both to the system and to the users themselves. The information gathered was supplemented by data obtained from the transaction logs. Findings-The results have revealed the use made of the OPAC and the characteristics of the searches performed. Users are still confronted by classic problems of information seeking: information overload, errors in subject searching, and the predominant use of the system's simpler options. The results show that the OPAC is broadly used by end-users not only for obtaining printed material, but also for connecting to the electronic resources subscribed to by the library. Originality/value-The OPAC should continue to occupy an important position in the library's overall information environment, interacting with other information systems.

Recibido: 15 de noviembre Aceptado: 5 de diciembre Resumen Durante los veranos de 2012, 2013 y 2014 TVE repuso, en su segunda cadena y en horario de sobremesa, dos de sus series más populares: Curro Jiménez y Verano Azul. Desde su estreno, en 1975 y 1981, respectivamente, ambas series se han reemitido, total o parcialmente, en varias ocasiones en las décadas de los 80 y 90. Sin embargo, para su reposición en el siglo XXI ha sido necesario someter a estas series a un proceso de remasterización que garantizara los actuales estándares de calidad para la emisión. La remasterización permite obtener del soporte original cine, después de una serie de procesos técnicos y documentales, copias en HD (Alta definición) adecuadas tanto para su emisión por los circuiros tradicionales (Primera y Segunda Cadena o Canales Internacionales de TVE) como para su posible comercialización. Este trabajo describe, esencialmente, los trabajos documentales y los procesos técnicos necesarios para la recuperación de los fondos fílmicos de programas no informativos que se realizan en el Fondo Documental de TVE.

From their first releases in 1975 and 1981, both series have been rebroadcast either in part or in full during the decades of 1980 and 1990. However, their 21st century releases differ from the previous ones since the image quality has been improved thanks to a remastering process that enables the replication of current broadcast quality standards. The remastering practice includes different technical and documentary procedures that enables cinema rolls to be converted to HD copies suitable not only for the traditional broadcast networks (in this case first, second and international TVE channels), but also for commercial purposes. This paper describes the TVE Audiovisual Archive's technical and documentary procedures used for the non-informative archive recovery program.

Evaluation campaigns provide a common framework with which the progress of speech technologies can be effectively measured. The aim of this paper is to present a detailed overview of the IberSpeech-RTVE 2022 Challenges, which were organized as part of the IberSpeech 2022 conference under the ongoing series of Albayzin evaluation campaigns. In the 2022 edition, four challenges were launched: (1) speech-to-text transcription; (2) speaker diarization and identity assignment; (3) text and speech alignment; and (4) search on speech. Different databases that cover different domains (e.g., broadcast news, conference talks, parliament sessions) were released for those challenges. The submitted systems also cover a wide range of speech processing methods, which include hidden Markov model-based approaches, end-to-end neural network-based methods, hybrid approaches, etc. This paper describes the databases, the tasks and the performance metrics used in the four challenges. It also provides the most relevant features of the submitted systems and briefly presents and discusses the obtained results. Despite employing state-of-the-art technology, the relatively poor performance attained in some of the challenges reveals that there is still room for improvement. This encourages us to carry on with the Albayzin evaluation campaigns in the coming years.
