In order to determine the suitability of packaging materials made of paper/cardboard and used in different public institutions in charge of Costa Rican documentary heritage, the measurement of the acidity (pH) of the materials was carried out, as well as the use of infrared spectroscopy to study the changes in the crystalline structure of paper cellulose molecules, which influence the oxidation and degradation of cellulose as a consequence of aging (Chiriu et al., 2018). Studying the materials used to package and store documents with historical/heritage value is of high importance since these are the ones that remain in direct contact with the cultural assets for years, even decades. In total, the measurement of the physicochemical properties was carried out in four different aging stages (0, 8, 15 and 28 days), in order to compare the results and establish the changes and degradations in the materials, this to determine which of the sampled materials are more suitable for packaging documentary heritage, both in the short and long term, and according to the parameters analyzed.

This study proposes a methodology using OpenAlex (OA) for tracking Open Access publications in the case of Argentina, a country where a self-archiving mandate has been in effect since 2013 (Law 26.899, 2013). A sample of 167,240 papers by researchers from the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) was created and analyzed using statistical techniques. We estimate that OA is able to capture between 85-93% of authors for all disciplines, with the exception of Social Sciences and Humanities, where it only reaches an estimated 47%. The availability of papers in Open Access was calculated to be 41% for the period 1953-2021 and 46% when considering exclusively the post-law period (2014-2021). In both periods, gold Open Access made up the most common route. When comparing equal periods post and pre-law, we observed that the upward trend of gold Open Access was pre-existing to the legislation and the availability of closed articles in repositories increased by 5% to what is estimated based on existing trends. However, while the green route has had a positive evolution, it has been the publication in gold journals that has boosted access to Argentine production more rapidly. We concluded that the OA-based methodology, piloted here for the first time, is viable for tracking Open Access in Argentina since it yields percentages similar to other national and international studies.

Nowadays, the Spanish International Book Fair (LIBER) is not very popular, and it is redefining its own role within the Spanish publishing field. However, LIBER is still a suitable event for Spanish and Latin America distributors. This work deals with these issues informed by a field work carried out in the fair during the last months of 2017. LIBER'2017 had also Argentina as Guest of Honour, which performance is analysed in detail in this paper. [ABSTRACT FROM AUTHOR]

New digital technologies have modified the way scientific knowledge is being communicated. This work intends to evaluate the impact of a socio-digital communication plan implemented for the journal Arqueología (Facultad de Filosofía y Letras, Universidad de Buenos Aires), designed to boost the distribution and outreach of published content in the digital ecosystem. We proposed a method to evaluate the journal's visibility in social networks, website user behavior and the impact of the published content from 2018 to 2022, based on different altmetric and bibliometric indicators. The results of said analysis show that the effects of the pandemic coupled with the implementation of a dissemination strategy increased the journal's visibility in social networks, which in turn produced an increase in the number of views and downloads of its papers. These findings highlight the importance of considering various types of online interaction to better understand the academic impact of scientific research. [ABSTRACT FROM AUTHOR]
