Dear AoIR members, Pleasure to share with you the open access book "The Many Faces of Data Access: Legal and Policy Implications for Research <https://networkcultures.org/blog/publication/themanyfaces/>", published by the Institute of Network Cultures <https://networkcultures.org/>. My colleagues Pedro Amaral, Marcos César, and I have contributed with a chapter on surveillance and government transparency called: "Keys thrown away? Challenges in Brazil on Accessing Public-Interest Data on State Surveillance Tools via Transparency Portals and Requests for Information". The chapter explores a study we published in 2022 on contracts between the Brazilian government and hacking tools' vendors, especially the structural challenges on accessing the minimum information from the administration. Hope you enjoy it. Best regards, -- *André Ramiro* PhD Candidate in Informational and Public Law at Hamburg University.
