This research protocol was used for an academic master's degree research, the objective of which was to analyze the current panorama of Brazilian public libraries regarding the adoption and provision of Information and Communication Technologies (ICTs), from the perspective of the libraries themselves, for the management of its operations and for the provision of information and communication resources and services to its end users. This study is developed in three main phases. In Phase 1, a bibliographic and exploratory research was carried out on public libraries, focusing on the purpose, resources, services, information and communication technologies (ICTs) used, and experiences of adopting these technologies in Brazil and abroad. Sources include databases such as LISTA with FT, Brazil CAPES Theses and Dissertations Catalog, NDLTD and BRAPCI. Phase 2 involved descriptive research using an online questionnaire to identify ICTs adopted by Brazilian public libraries. Invitations were sent by email to libraries registered with the National Public Library System (SNBP). The sample selects five libraries from each macro-region of Brazil, prioritizing the most populous cities according to The Brazilian Institute of Geography and Statistics (IBGE) data. The questionnaire addresses dimensions such as operations management, information resources and services, and communication. In Phase 3, the collected data was compiled, presenting it in analytical and graphical tables. The results were compared with bibliographical research to understand the ICTs adopted by public libraries. The final phase discussed the results in relation to the research objectives, contributions to the field, study limitations, and recommendations for future research, culminating in a final summary.
