The aim of this work is to know the degree of insertion of bibliographic, institutional, and person identifiers in the bibliographic control process in national libraries and/or national bibliographic agencies of the Latin American countries that are members of the Association of Ibero-American States for Development of the National Libraries of Ibero-America (ABINIA), -Spain and Portugal are excluded-. The study was based on website research with a qualitative strategy around the analysis of identifiers. We proceeded to consult, observe, read, analyze and interpret the web pages of national libraries, national bibliographic agencies and the official websites of each of the identifiers. The results and conclusions show that Latin American national libraries rely solely and exclusively on two bibliographic identifiers for the registration of legal deposit and the preparation of national bibliographies: the ISBN (books) and the ISSN (periodical publications) and, to a lesser extent, in the ISMN (music publications, sheet music, etc.). The inexistence of networks of bibliographic agencies and agencies that manage identifiers that work collaboratively with national libraries show the limitations that exist in the dissemination of documentary heritage and, therefore, the limitations to be able to carry out exhaustive universal bibliographic control.

Presentation of the main types of literature reviews and elements to decide which is most suitable in each case. Traditional or narrative reviews are described on one hand, and the differences between systematic reviews and scoping reviews are explained. Recommendations for the most appropriate use of each are proposed.

The lack of reference works that compile the early years of the rock-pop movement in Argentina has caused the invisibility of most of the pioneer musicians and groups. The official historiography has given little importance to the musical productions prior to the recording of the song "La Balsa" by Los Gatos in 1967, which led to a large part of this history remaining hidden. In recent years numerous academic studies have addressed this issue, giving a new look at the emergence of the origins and consolidation of the so-called "National Rock". Librarianship, through its search techniques and access to information, plays a fundamental role in the search and organization of documents to shed light on the diffuse origins of rock in our country. This individual project (in progress) aims to investigate this period, and generate a biographical dictionary on the origins of the rock/pop movement in Argentina, compiling soloists and bands that emerged between 1955 and 1973 that foreshadowed the future "National Rock".

The COVID-19 pandemic impacted the daily work of all citizens, especially in our libraries, since, after the Social, Preventive, and Mandatory Isolation (ASPO), in a short time, they were forced to adapt their activities so that they could be carried out remotely. In the case described, although a great impact on the operation of the library was expected, according to the statistics after one year, it was noted that, although the transactions had decreased, the usual activities had developed normally and its quality had not diminished thanks to the technological advantage of the institution in general and of the library's reference service in particular.

Spanish newspapers as a reference source of Wikipedia. Spanish Wikipedia ranks ninth among the most consulted websites. The most frequent queries are about: celebrities (athletes, artists, politicians, etc.); movies and television series; places; or sports, among others. Many of these issues require analmost continuous update. The official policy of the Wikipedia declares that “specialized sources should have priority overthe general press, since newspapers and weekly magazines tend to simplify their exposition, sometimes omitting importantdata or describing the subject in an encyclopedically unhelpful way”. The article analyzes the extent to which Wikipediarespects this policy by analyzing the presence of some of the most important Spanish newspaper media in Wikipedia as asource of external reference. How many articles, and what percentage, of the Spanish Wikipedia have references or citations to the Spanish digital newspapers most consulted on the internet? On what types of contents of Wikipedia, from thethematic point of view, are Spanish digital newspapers used as an external source?

Pedagogical researches are the cornerstone of the improvement of the teaching-learning process in the universities; its results must be widely disseminated so that they are useful at a global level. The Google Scholar (GS) is one of the most used scientific information systems to disseminate these results on the Internet. The objective of this study was to determine the visibility and scientific impact of Cuban pedagogical research based on the user profiles of the GS. The methodology was based on a bibliometric analysis of these profiles belonging to professors and researchers of the six Cuban universities with presence in the Regional QS Ranking for Latin America. It was concluded that the facilities offered by the GS to increase the visibility and scientific impact of Cuban pedagogical research have not been sufficiently exploited. Consequently, strategies must be implemented that increase the digital bibliographic identity of these professors and researchers.

Title: The Journal Citation Reports (SCI edition) with and without journal selfcitations. Journals are ranked in the subject categories of the Journal Citation Reports (JCR) according to their impact factors (JIF). The calculation of this indicator includes both citations received from other journals and self-citations from the journal itself. In this paper the current model of the JCR is compared with an alternate model using the JIF without self-citations as a variable. In order to do this, simulations were carried out using JIF without self-citations as an alternative variable. We studied the relationship between the two variables (JIF with self-citations and JIF without self-citations), the gain obtained by the journals with the usual JIF with self-citations, the changes in the ranking in the whole JCR, and changes in the internal ranking in the JCR’s subject categories. A small negative correlation was found between the gain that the journals obtained and their JIF. The results obtained suggest that if JIF without self-citations were used as the variable, the ranking of journals in the JCR and within the subject categories would be, in general, very different from the current one. The quantification of these differences is one of the more interesting results of this work.

The public library fulfills a permanent formative role in the field of knowledge and culture, one of its main objectives is to meet the needs of the community in which it is immersed. Through the provision of various services, one of them being the local issues section, which is responsible for providing citizens with all the information related to the history of the community in its different manifestations. This paper exposes the importance of the contribution and social projection provided by this section contextualizing its work in the population of Simat de la Valldigna in Valencia, Spain. There are also described, by means of examples, different materials that make up this information reservoir. It concludes by highlighting the responsibility of the public library in keeping alive the local history of Simat as a contribution to the preservation of the memory of their ancestors.

This paper presents an experience of standardization in the development of subject guides for the Information and Technology Center (CITec), Faculty of Natural Sciences, Río Piedras Campus, University of Puerto Rico. Thematic guides are information resources that support research in different disciplines. CITec needed to update their own guides and develop new ones. To work the initiative, we used an open source tool and applied the systematic, planned and structured five phases of the ADDIE model consisting of analysis(A), design(D), development(D), implementation(I) and evaluation(E), to both the guides and the whole work. As a result, topic and specialized guides were developed, letting users retrieve reliable information from the SubjectsPlus open source platform. The realization of the project facilitated the standardization of the guides, their online creation and immediacy of their updates via their website.

There are two methods of retrieving information from documents in the field of genomic science and medicine in general, namely: 1) through the combined use of associations determined by the Medical Subject Headings, and 2) by employing specific terminologies, such as in folksonomies, alternative medical-genomic terms in use in the general language, or acronyms or apocopes from the genomics field. To some extent, many thinkers and indexers hold that the combination of two methods may be the best approach. While few authors advocate for keeping the structure of controlled vocabularies, built up over many years of content interpretation, unchanged, there are numerous proposals for expanding the search horizons of thesauri, whether through social cataloging, algorithmic domain analyses that contrast indicators or the semantic web using markers of meaningful semantic lexicons contained in digitized text.

This work is based on a survey of the existence and characteristics of the virtual reference services offered by the national university libraries of Argentina visible on the Web and the use of Web 2.0 tools in the provision of these. Data was collected from 297 libraries corresponding to 50 university institutions in Argentina. A bibliographic review of concepts and types of virtual reference services has been taken as a theoretical framework. The analysis was made through the evidence, collected between April and June 2018, on institutional websites. It was used as an instrument to systematize the observation, a form created ad hoc. The results show an increasing use of social networks and other tools of the social Web, having observed in many institutions the inclusion of a large amount of contact data with users and the intention to make visible the offer and the options of non-contact reference to through websites and blogs.

Our aim is to identify the steps that librarians can take concerning altmetrics within the framework of the research support services. The current bibliography on altmetrics has been reviewed. A survey has also been carried out of librarians of Spanish universities to find out their degree of involvement in the matter and the setting up of relevant initiatives. Likewise, a thorough study which would enable librarians to find out about the use which their researchers make of social networks and the interest that they may have in altmetrics is needed. This research offers a user guide for librarians as an orientation in their activities and initiatives related to altmetrics, as well as a list of arguments which justify the reasons why librarians should undertake these initiatives. We contribute a view of altmetrics from the perspective of librarians as a strategic element of dissemination and training in altmetrics.

The realization of the entry "territorial development" for Wikipedia is described during an editaton of the National Institute of Agricultural Technology (INTA), where librarians and researchers participated.

The article presents an analysis on the science results and innovation obtained in the University of Oriente during the period 2011 at the 2015. The investigation, of exploratory character, combines quantitative and qualitative methods, to determine the main difficulties related with the behavior of this results. The derived conclusions of the analysis indicate that they exist inadequacies that have their base in the form in that has been developed the administration of the process of scientific investigation and their evaluation, during that period, revealing opportunities for a methodological intervention in this administration.

The existence of multiple digital newspaper libraries and press repositories, not all duly standardized, presents not a few difficulties for the location and access to the informative wealth of our historical press. This demands great efforts from both the curious and the researcher.

Choose between "e-learning", "digital learning" or "virtual learning" as a keyword for a scientific article can be a dilemma for a researcher who does not know the management of a thesaurus which should normalize the keywords of your contribution. So far, the selection of key words with greater or lesser success is a requirement that scientific journals make their authors and they consider them a procedure more in preparation for shipment of an item. Today, with the ability to search the full-text articles, is it useful to continue considering?

Title: InfoSud Digital: a virtual reference service for cooperative development. InfoSud Digital promotes social awareness of interna-tional development collaborations. A VRS (Virtual Reference Service) using the Question Point tool from OCLC was created for this purpose. The ultimate goal is to create a network of information and documentation on cooperation for development. InfoSud Digital is a project developed by InfoSud, the information centre of the Patronat Sud-Nord of the University of Valencia

Digital reference is the service offered by libraries and information centres so that users can ask questions through the Internet. The concept of digital reference is described, along with the different typologies based on various criteria. The technologies used today for receiving questions and sending answers are presented. Guidelines are suggested for implementing a digital reference service, based on four criteria: the actors involved, the techniques used, the available resources and the management of the service. It concludes by highlighting the value of digital reference as an online service that expands the range of patrons.

The "drone mania" started. These technological flying machines are becoming slowly in a common "toy" for teens and adults geeks. But what is a drone?. It is the symbol of an unmanned aerial vehicle, known as UAVs, which is managed through a remote device. These devices can be used for research, security, leisure, geography, journalism, audiovisual production, major disasters, however its use is potential. The big question is whether these flying objects will libraries in Latin America. But I dare more: they are necessary for the information units?. What types of services could include these devices?. Why not?. Libraries should be at the forefront of technology with respect to reducing the large digital and information gap that prevails in our continent.

This article analyses digital reference services and offers definitions of the concept as well as recommendations about quality criteria and standardisation. A discussion follows covering the most important technologies from e-mail to web contact software that integrates e-mail, chat, MOO’s, videoconferencing and web co-navigation together with other functionality. The author describes the main projects developed in this area in the US and the UK, as well as specific experiences from Spain.

After a detailed review of the literature on the evaluation of reference services in academic libraries, we describe the evaluation process of the Reference Service of the University of Seville’s library, in both its onsite and virtual models, during two time spans in 2011. We analyse the results using an adapted version of the READ scale. The predominance of the system’s onsite model was confirmed, with the type of service characterized by short questions of a basic nature, quite evenly distributed between the morning and afternoon, with a duration of less than five minutes, with the questions coming predominantly from students and answered by non-specialist staff.

Title: "The reference service and the reference librarian". Detailed theoretical presentation of a reference service and reference work. ¿What is it? ¿How did it develop? ¿Who does this reference work? and so on as well as the stages (the reference process) the reference librarían goes through in an attempt to answer effectively and economically the questions put forward by users.

The following article will comment the experience of the library Joaquín V. González of the Facultad de Ciencias Jurídicas y Sociales of the Universidad Nacional de La Plata (Argentina) in the implementation of a virtual reference service by chat, to answer requests in real time, directed to the university community.
