The Scientific Journal Publishing Floor 21 dedicates this space to the publication of chapters of books, monographs, dissertations and theses in the format of e-books of the most diverse areas of knowledge.

For all works will be assigned the individual digital object identifier- DOI® of scientific production through Crossref. This identification will allow greater academic visibility, security against plutogio, indexing of the published work and inclusion of the work in the author's Lattes. The author, in possession of the e-book in PDF, may print or disseminate in digital format his work. All e-books will have a custom cover.

The writings must be sent in word format via e-mail:rrecima21@gmail.com so that we can carry out the budget survey before publication.
