Editorial Sol90, S. L. is a publishing and editorial entity that appears under a collective byline. Public information about it is currently limited, and its exact founding date, location, and staffing are not clearly documented. Judging from the two works held in the collection, Birds (Volume 1) and Birds (Volume 2), the organization's editorial focus lies in popular science, particularly natural history and animal subjects. These two works center on birds and are presented in two volumes, reflecting a systematic approach to organization and a multi-volume editorial strategy that allows readers to build knowledge step by step. As a collective byline, its role is closer to content planning and editorial publishing than to individual authorship. Based on the available material, the organization has some practical experience in organizing and compiling popular science reading materials for general readers, with attention to clarity and readability, though its overall influence and publishing scale await further public information.
