Interview with the professor of the University of Barcelona Dr. Javier Guallar on the occasion of the first 100 issues of his Sunday newsletter "Content Curators" on meta-curation of content, published on the Substack platform. Contents: Biographical note, Creation and evolution of the newsletter, reference to other newsletters on similar topics (Communication, Social Networks, Internet, New technologies, Artificial Intelligence, etc.), Common topics, User statistics, Work system, Methodology, Feedback received, Challenges, Recommendations, Future. The interview was published on the Blog of Ediciones Profesionales de la Información SL.

Aim: The paper aims to present the current state of information services in the Provincial Public Libraries (hereinafter: PPL). As a comparison and presentation of this issue, we will selected university books also to examined in a broader background. The will be allowed to answer questions about differences and similarities between them. We will also be able to indicate the pros and cons of solutions used in both types of books. Research methods: An analysis of the presence of information services in the organizational schemes of libraries has been carried out, we checked the premises and opening hours, as well as the tools and information forms of education offered by employees. The basis for the research was the content contained on the library websites and in the Public Information Bulletins. The analysis we subjected to 18 PPL. For comparison purposes, the selected 18 academic books in voivodship cities we examined in the same respect. The same research covered 36 units. Besides, a literature analysis devoted to the issue of scientific information in libraries we used. Results: The analysis showed that information in PPL is more regional than scientific, which is a difference compared to academic books. What unites both types of libraries is the lack of a unified solution for information in public libraries, but also in academic ones. Academic libraries have better work tools. Only a few PPL have foreign, paid databases, which are the norm in university libraries. Those created by PPL are available for free on the Internet. Conclusions: Between the public and academic books there is a big difference in their information function. It is likely that the process of transforming public libraries into community centers and community centers as part of the "third place" idea will further deepen this difference. The question is, will we be able to continue to talk about scientific information in the public library in a dozen or so years?

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.

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 aim of the study is to identify, analyze and evaluate changes and trends in the use of collectively created on-line Wikipedia Encyclopedia (http://www.wikipedia.org/) within the framework of the Czech virtual reference service „Ptejte se knihovny“ (Ask Your Library) (http://www.ptejteseknihovny.cz/). Survey sample consists of the records in the archive of the answered questions from the years of 2003 to 2012 published in a freely accessible on-line archive of the service „Ptejte se knihovny“ (Ask Your Library) (http://www.ptejteseknihovny.cz/archiv) that include references to the Wikipedia entries and also the links to Wikipedia from the all archive records (i.e. regardless of their location in the archive records). The first step of the survey has been to find out the number of archive records with references to Wikipedia, the number of the references to the encyclopedia and the types of Wikipedia entries. Those records have been analysed using the method of bibliometric citation analysis. The author publishes the results with her own commentary. The basic hypothesis of the survey states that the extent of use and citing of the Wikipedia data within the service „Ptejte se knihovny“ (Ask Your Library) has been steadily increasing, especially the use of the Czech language version of the encyclopedia, and that the extent of use and citing of other selected major general encyclopaedic works produced in a traditional way (printed or on-line) is substantially lower than that of Wikipedia. The results of the survey partially affirm increasing use of the Wikipedia as an information and reference source not only by general public, but also by librarians and information officers.

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?

Question answering (Q&A) sites, where communities of volunteers answer questions, may provide faster, cheaper, and better services than traditional institutions. However, like other Web 2.0 platforms, user-created content raises concerns about information quality. At the same time, Q&A sites may provide answers of different quality because they have different communities and technological platforms. This paper compares answer quality on four Q&A sites: Askville, WikiAnswers, Wikipedia Reference Desk, and Yahoo! Answers. Findings indicate that: 1) the use of similar collaborative processes on these sites results in a wide range of outcomes. Significant differences in answer accuracy, completeness, and verifiability were found; 2) answer multiplication does not always result in better information. Answer multiplication yields more complete and verifiable answers but does not result in higher accuracy levels; and 3) a Q&A site’s popularity does not correlate with its answer quality, on all three measures.

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.

Purpose: This study aims to examine answers’ quality on the Wikipedia Reference Desk, and to compare it with library reference services. It examines whether Wikipedia volunteers outperform expert reference librarians and exemplify the paradox of expertise. Design/Methodology/Approach The study applied content analysis to a sample of 434 messages (77 questions and 357 responses) from the Wikipedia Reference Desk and focused on three SERVQUAL quality variables: reliability (accuracy, completeness, verifiability), responsiveness, and assurance. Findings The study reports that on all three SERVQUAL measures quality of answers produced by the Wikipedia Reference Desk is comparable with that of library reference services. Research limitations/Implications The collaborative social reference model matched or outperformed the dyadic reference interview and should be further examined theoretically and empirically. The generalizability of the findings to other similar sites is questionable. Practical implications Librarians and library science educators should examine the implications of the social reference on the future role of reference services. Originality value This study is the first to: 1) examine the quality of the Wikipedia reference desk; 2) extend research on Wikipedia quality; 3) use SERVQUAL measures in evaluating Q&A sites; and 4) compare Q&A sites with traditional reference services.

Today information is sought first of all in the internet – and even regular library users do nothing different. Libraries have adapted themselves to this and have built up virtual sub-branches on the net with online-catalogues, digital libraries, full-text databases and direct interlibrary loan. A new addition to this palette is "DigiAuskunft" (digital information). It started up as planned at the beginning of 2006 at the Dortmund City and State Library, and soon thereafter at the Cologne University and City Library, the University Library of Dortmund, the Cologne City Library and, since April, at the Technical College of Cologne. At each library site a few, but not particularly exhaustive preliminaries were necessary: modification of the web-based blank forms, creation of text modules and signature blocks, development of the knowledge database and establishing local text modules. An internal mailing list was set up among all users to help solve initial problems and discuss software improvements. The system has proven its worth in the practice. The processing of reference inquiries has been considerably simplified and can be accomplished from any internet PC. About 80 percent of the inquiries deal with local topics related to the respective library (regarding the collection, the individual user account, and specific services). Pure reference questions, such as that from a user in Amsterdam seeking an article about Westphalia history, are still rather scarce. Hence it has rarely been necessary to forward an inquiry to the entire network. In the course of this summer 18 more libraries will join the online network, and there are more getting ready on the sidelines.

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.

Objectives. To describe and evaluate the use of Wikipedia links to digitized collections held in libraries, archives and other cultural institutions. Methodology. The study examines all the articles included in the Spanish and Catalan versions of Wikipedia, using a wiki analysis tool. A broad selection of 81 Spanish digital collections of varying sizes is then made. Data are taken from other digitization projects for a comparison of results. Results. The use of links from Wikipedia remains relatively unexploited, with the exception of those to the Miguel de Cervantes Digital Library, where the scale of use is markedly greater. Some specialized collections are more frequently used, but in general there is a lack of attention paid to these collections by the team of Wikipedia editors. This needs to be taken into account in the development of digitization projects in line with the Europeana portal.

Any investigator, with a superficial knowledge of the information recovery systems can make a bibliographical search in Internet through his computer and obtain results than more sufficient, with respect to the amount of references. Other thing is that these results respond, in their content, to which the investigator really looked for, or are all exhaustive that possible. A pertinent search of data must, through an excellent analysis of the results, lead to consistent and useful syntheses. Therefore, it will be necessary to formulate a suitable strategy that allows that the results are simultaneously excellent and "revelances".
