Índices Berovides y Wally: métricas de productividad y uso alcance para evaluar editoriales y autores cubanos en eLibro durante el curso 2024–2025

Introduccion: The Berovides, Wally, and Medium Impact Wally indices enable the evaluation of productivity and digital usage of publishers and authors on platforms such as eLibro.Objective: To evaluate the productivity, digital usage, and reach of Cuban publishers and authors in the eLibro Digital Library during the 2024–2025 academic year using the Berovides, Wally, and Medium Impact Wally indices. Methodology: A bibliometric study applying the Berovides Index (based on the number of published titles), the Wally Index (based on digital usage and reach data: visits, downloads, unique users, etc.), and the Medium Impact Wally Index (ratio of digital usage and reach to the number of titles). Logarithmic normalization and natural cutoff models (linear and exponential) were used to define terciles and quartiles. Results: A total of 1,621 unique publishers and 96,912 first authors were identified. Of these, the 32 Cuban publishers with the highest productivity and the 29 Cuban authors with more than 7 titles were analyzed in depth. Twenty publishers were placed in the high and medium digital impact quartiles, led by Editorial Universitaria (Wally: 0.86). Fifty-four authors reached the high-impact quartile, notably Caridad Fresno Chávez (Wally: 0.93). According to the Berovides Index, 23 publishers and 53 authors were placed in the first productivity tercile, with Editorial Universitaria and Pedro Horruitiner Silva being the most productive. Conclusions: The Wally Index is effective for measuring the digital usage and reach of publishers and authors who publish in eLibro. The Berovides Index complements the assessment by measuring productivity. Both offer an integrated perspective useful for evaluating academic performance. The Medium Impact Wally Index adds an average intensity per title perspective.
