This study analyses the techniques and procedures that were developed and the changes that took place in the National Autonomous University of Mexico (UNAM) and the Autonomous University of Puebla (BUAP), both in Mexico, and the University of Minnesota Duluth (UMD), in the United States of America. To face the crisis of the COVID-19 pandemic, librarians in these institutions improved their Information Literacy (IL) and Media Information Literacy (MIL) programmes. Design/methodology/approach: This study has a mixed methodology with a comparative analysis. For this purpose, data shows the universities' contexts: the communities of students, teachers, researchers, and librarians, and the e-learning strategies of IL and MIL programmes. Findings: As part of the results of the crowdsourcing collaboration between the UMD, UNAM and BUAP, the study shows the different online learning communities and their innovations. Originality: Although there is theoretical knowledge about IL and MIL in Mexican universities and University of Minnesota Duluth, the e-learning strategies used by their librarians in this document sought to provide technical solutions and other options for a virtual work scheme that responded to the specific problems presented by COVID-19. In this case, the framework for creating online library services was designed by their librarians for their communities in the context of the current crisis, even when online services had already been established for more than ten years. Research limitations/implications: The technological infrastructure, the professionalisation of the library staff and a lack of knowledge of the new virtual teaching-learning needs. Practical implications: Analysis of tools for virtual teaching-learning services, description of strategies used by library staff, results and feedback. Social implications: IL and MIL strategies created in a variety of contexts can be enhanced by library collaboration in a fully virtual setting. Libraries with better technological infrastructure play a decisive role.
