In order to evaluate the use of library resources and services by the students of the Technological Institute of Sonora and determine their level of general satisfaction with library services, a quantitative investigation was carried out, with a non-experimental design, transversal type and with a descriptive scope. The population was made up of undergraduate (N = 17,532), master's (N = 414) and doctorate (N = 72) students, a total of 18,818 students enrolled in August 2019 in the Obregón, Navojoa and Guaymas Academic Units of said university. The instrument used was designed for this perception assessment exercise, which consists of 25 multiple-choice and 1 open-ended questions. A total of 1,454 valid responses were obtained that averaged a satisfaction level of 4.00 points, which means that users are “satisfied” with the services received in the evaluated cycle. It is recommended that these numerical indicators be used to increase satisfaction in the areas that were well evaluated, but, on the other hand, corrective actions should be taken in those services whose mean has been the lowest.
