It deals with the empirical study of the Ceará State Public Library, located in the Praia de Iracema neighborhood,

and the Dolor Barreira Municipal Public Library, located in the Benfica neighborhood, both in the city of Fortaleza,

in the State of Ceará, as mediation environments for memory. Information mediation is an action of dialogue

between the role of the public library and the process of preserving and disseminating memory in the capital 

of Ceará. The public library as an institution that holds the memory of a people, brings in its repertoire, stories

 and memories, that is, the recognition of the past, mainly in the books, magazines and newspapers of the 

time and finds it in the present, with new information technologies and communication new possibilities of 

presenting in the most varied existing supports and with IT resources, converting physical elements and 

materials into virtual reality. Libraries, now under study, have carried out, over time, activities that seek to 

lead the local community and society in general to reflect on history, daily life and cultural life, using various 

programs, almost always culminating with the dissemination of the collection. The problem is based on the

following question: What is the role of the public libraries in the capital of Ceará, the State Public Library 

of Ceará and the Dolor Barreira Municipal Public Library in the development of the memory of the 

neighborhoods of Fortaleza? The general objective is: to investigate the mediation practices of the 

aforementioned libraries for the preservation and dissemination of the memory of the neighborhoods

of Fortaleza, aiming at the proposal to create a cooperative service between the two libraries aimed 

at preserving the memory of the neighborhoods of Fortaleza. The specific objectives are: a) identify the 

services that the two referenced libraries have performed in terms of mediation; b) characterize the services 

that cover other neighborhoods in the city of Fortaleza carried out by the highlighted libraries; c) understand 

how the mediation of cultural memory works in the spaces of these libraries aimed at preserving the memory

of the neighborhoods of the capital of Ceará. Bibliographical research was carried out where topics related to 

memory, information mediation and the public library are discussed, observing theoretical and conceptual 

aspects. Considering the contributions of authors such as Halbwachs (1990), Nora (1993), 

Almeida Júnior (2009, 2015, 2020, 2021), Silva e Ribeiro (2010), Silva (2015, 2016) and others. 

The methodology is qualitative in nature, characterized in terms of descriptive objectives and technical 

procedures in bibliography. A questionnaire and semi-structured interview with managers and information 

professionals were used as methodological resources.
