Dear colleagues, after the first year in production, from the Library of the University of Cádiz we decided to share our experience on migration from Millennium ILS to Koha by publishing a paper in the Spanish professional journal “El profesional de la Información”. Implementing Koha at the University of Cádiz Libray. Fernández-Alfaro, Leonor; Márquez-Pérez, Aurora; Chamorro-Rodríguez, Ricardo (2018). "Implementation of Koha in the Library of the University of Cádiz". The professional of the information, v. 27, n. 4, pp. 928-936. https://doi.org/10.3145/epi.2018.jul.21 As our situation is similar to that of many other libraries that are currently in analogous processes, we encourage you to read them as we describe the different phases of the Project: the choice of software, migration, parameterization and a final consideration as a conclusion. We hope our experience will be useful to you and, of course, we are at your disposal for any question you want to ask us. Kind regards.
