Copyright and conditions for accessing content

Welcome to the Digital Library of Theses and Dissertations of the University of São Paulo (BDTD), a repository for the intellectual output of the University of São Paulo (USP). This page establishes the general guidelines, rights, and conditions governing access to, consultation of, and use of the scientific and academic works made available here.

1. Copyright and intellectual property

All intellectual output hosted in this repository is protected by the Brazilian Copyright Law (Federal Law No. 9,610 of February 19, 1998) and applicable internal regulations.

The moral and intellectual rights to the works belong entirely to their respective authors.

2. General conditions of use

Unless otherwise stated on the individual page of each work, viewing and downloading files are authorized exclusively for the purposes of:

• Private study, teaching, and research;
• Criticism, analysis, and scholarly citation, provided that the requirement to attribute authorship is respected and the original publication source is acknowledged.

The following is expressly prohibited:

• The sale, full reproduction, distribution, or commercial exploitation of any work in this repository without the author's prior, express, written permission.

3. Access rights regimes

In accordance with institutional policies promoting open science, access to works in this repository is divided into two regimes:

• Permanent public access (default): the work, its metadata (abstract, keywords, and authorship), and the full-text file are available for public access worldwide from the date of publication on the BDTD portal.
• Restricted access (temporary embargo): upon formal request by the author and in accordance with internal regulations (CoPGr Resolution No. 7569 of October 3, 2018, in Portuguese), the complete digital file of the work may be kept restricted (under embargo) for a specified period. During the embargo, only the descriptive metadata and a simplified version of the work will remain publicly visible. The full-text file will be released automatically for public access when the period specified by the author expires.
