The Federal Agencies Digital Guidelines Initiative (FADGI) published the third edition of its digitization guide for cultural heritage materials in May 2023. This resource details best practices for digitization to ensure the preservation and accessibility of bound resources, loose documents, maps, photographs, negatives, and other paper-based materials. The guide is an open-access document available for free, in which specialists from the Library of Congress and professionals in photography and color science have compiled objective, measurable characteristics of image quality. Additionally, this group of experts has outlined workflow activities to ensure the most accurate representation of cultural and historical materials. This review aims to highlight key points from this 129-page guide to provide cultural institutions with a valuable resource for planning digitization projects or improving existing initiatives.

This study analyzes the Puerto Rican scientific production in the field of mental health from 2000 to 2022, using bibliometric indicators. PubMed® was utilized to obtain data yielding 485 documents published in 241 journals. Production showed a linear increase starting in 2011 and peaking in 2022. Collaborative publications represented 66.8% of the total, with national collaborations (66.05%) predominating over international ones (33.95%). The two leading local journals in terms of output were the Puerto Rico Health Sciences Journal (n=45, 9.28%) and the Boletín de la Asociación Médica de Puerto Rico (n=25, 5.15%). The most common research topics were related to substance abuse disorders, risk factors, and child mental health. This analysis highlights the need to strengthen scientific research and its visibility in Puerto Rico through policies that promote greater collaboration and institutional support in emerging mental health themes.

Reflexión en torno al profesional de la información y los diversos elementos que lo caracterizan y que provocan cierto grado de ambigüedad al definirlo. Se discute la tangencia de esta situación con otras profesiones como la tecnología educativa. El autor sugiere la aplicabilidad del concepto de consiliencia, acuñado por Wilson para esclarecer la naturaleza del profesional de la información. Señala la necesidad de que las organizaciones profesionales en este campo abran un espacio para los profesionales que tiene múltiples funciones y diversos escenarios de trabajo, incluso virtuales.

El Archivo General de la Nación data del periodo colonial Y su existencia ha sido accidentada por el conflicto bélico que le ha correspondido vivir (Guerra de la Triple Alianza, 1864-1870). Como pocas ciudades de América, Asunción fue asiento de conquistadores y colonizadores de la extensa región que abarcó después el Virreinato del Río de la Plata. Según palabras del historiador Carlos Pusineri Scala, existen más de dos millones de documentos antiguos en el archivo.

"Las bibliotecas constituyen comunidades, pero las comunidades de hoy en día forman una sola comunidad global. Asociarse como Biblioteca Hermana es una oportunidad para establecer relaciones con las bibliotecas de otras culturas que pueden ayudarnos a comprender, aprender y prestar un mejor servicio a nuestra propia comunidad." Lema de la American Library Association, en 1999, durante la presidencia de Sarah Long

Esta bibliografía selectiva incluye libros publicados en Puerto Rico en el 2001 y principio de 2002, independientemente de su tema o la nacionalidad del autor, así como libros de autores puertorriqueños publicados en el extranjero. Se incluyen algunos títulos de 1999 y 2000 que no aparecen en el volumen anterior de Acceso. Aunque abarcadora, la misma sólo refleja títulos adquiridos por el Sistema de Bibliotecas de la Universidad de Puerto Rico, Recinto de Río Piedras.

Desde su incorporación a la Federación Internacional de Asociaciones de Bibliotecarios y Bibliotecas (IFLA), ABGRA ha desempeñado un papel estratégico en la promoción del sistema bibliotecario argentino a nivel internacional. Este artículo analiza su participación en eventos clave como el Congreso Mundial de Bibliotecas de 2004 en Buenos Aires, el fortalecimiento de redes regionales, y su protagonismo en iniciativas globales recientes como la Conferencia MetLib. A través de estas acciones, ABGRA ha contribuido a posicionar a las bibliotecas argentinas dentro del ámbito bibliotecario global, fomentando el intercambio de conocimientos y la cooperación internacional.

Background and Aims: Phycological studies in the Mexican Atlantic have been aimed at understanding the benthic flora; however, the number of studies on epizoic algae is limited. The objectives of this work were to determine the species richness and composition of epizoic macroalgae for the Mexican Atlantic from data on the snail Stramonita rustica and through an exhaustive search of published phycological literature for the entire region. Methods: In 2018, 130 specimens of the gastropod Stramonita rustica were collected at Playa Hermosa, Veracruz, Mexico. A bibliographic review of studies in the Mexican Atlantic until 2024 was also carried out to obtain records of epizoic algae. Taxonomic identification of the phycoflora that grows on this snail was carried out, using external morphological characteristics and cross sections of complete thalli. Key results: Based on the literature review and specimens of the mollusk Stramonita rustica, a total of 117 taxa of epizoic algae were recorded in the Mexican Atlantic. These were grouped into 72 genera, 40 families, 21 orders and three divisions. The genera with the highest number of species were Ulva (6), Cladophora (5) and Chaetomorpha (5). At the family level, Rhodomelaceae (16), Cladophoraceae (11) and Ceramiaceae (8) stood out. The orders with the highest species richness were Ceramiales (32), Cladophorales (15) and Bryopsidales (15), which together represent 53% of the total algae recorded. Siphonocladus rigidus is presented as a new record for the coasts of Veracruz. Conclusions: The high richness of macroalgae documented in this work demonstrates that living animal substrates are a favorable site for their establishment and development, evidencing the need to elaborate studies that focus on the knowledge of algal epibiosis. In addition, the new record contributes to the knowledge of the biodiversity of the Mexican Atlantic, particularly in Veracruz.

Background and Aims: Melliferous plants are those used by the European bee, Apis mellifera, to collect nectar and honeydew, which combine with some enzymes to produce honey. The Asteraceae family is one of the preferred angiosperm groups by A. mellifera. Therefore, the objective of this work is to present a list of daisy species with beekeeping importance in the Central-West of Mexico, including its flowering time and distribution by state.Methods: A search for melliferous flora works carried out in the Central-West of Mexico was done in several electronic portals to generate a preliminary list. This was reviewed to update the nomenclature by discarding those species that are not distributed in the area and have not been recorded as exotic. Subsequently, herborized specimens were reviewed in the herbaria IEB and MEXU to complement the list. Moreover, photographs of plants in vivo were also taken in the north of Michoacán to illustrate some species used by A. mellifera.Key results: In the Central-West of Mexico there are 230 melliferous species of Asteraceae, of which 221 are native and nine introduced. Apis mellifera has a preference for six genera, Ageratina, Aldama, Bidens, Cirsium, Montanoa and Verbesina, which recorded each more than five species used by bees. Michoacán and Jalisco had the most species, with 120 and 99, respectively; in Querétaro and Zacatecas the records were minimal.Conclusions: The reduced number of melliferous Asteraceae registered in Querétaro and Zacatecas is mainly due to the lack of melliferous flora studies carried out in their territory. For this reason, it is necessary to continue documenting the plants of beekeeping importance not only in the Central-West, but throughout the country.
