Guidelines for Authors

People interested in publishing in Letras Verdes must submit their original works by registering in the portal

Articles must be original, unpublished works and not be approved or have been sent simultaneously to another magazine for its publication. Articles are received in Spanish and Portuguese English. The Editorial board reserves the right to decide on the publication of the works, as well as the number and the section in which they will appear.

General presentation of articles

The extension of the articles varies according to the section of the magazine to which it is sent, according to the following table:


Maximum of 8000 words, minimum of 5000 words


Maximum of 3000 words, minimum of 2500 words


Maximum of 8000 words, minimum of 5000 words

Articles must be presented in Times New Roman Font size 12, 1.5 points of space, with margins of 3 x 3 x 3 x 3 cm, in A4 page size format. This extension includes the summary, the body of the article, footnotes and bibliographical references.

The notes will be at the foot of the page, in Times New Roman font size 10 and with simple space format. In the case of acronyms, full meaning must be written the first time they appear. For example, “in the Latin-American Faculty of social sciences, FLACSO”.

Tables, graphs and maps must be fitted in place of the part on which you want to appear. Must have a title, sources and a sequential number, and always must be mentioned in the text. Please limit the amount of tables, charts and maps to 4-5 per article.

Avoid, as much as possible, the use of bullets in the text.

The evaluation mechanism explains in the section review Processes to itself for pairs.

Instructions for the adoption of keywords or descriptors

The keywords must be five to seven, separated by semicolons (;) and alphabetically. We recommend that the authors support themselves in the Unesco thesaurus.


Quote basic structure in text body.

In author-year system, reference in text normally appears between parentheses and contains only the first two elements that are recorded in references list: author and publication year, without punctuation between them. In addition, you can add number page or other localization element, after a comma. In no case use op. cit., ibid., ibídem.

(Leff 1994)
(Leff 1994, 91)

Entries from list of references with same author or authors and same year.

Papers from same responsible (regardless who is author, editor, compilator or translator) and same year should be differentiated with the addition of a, b, c, etc., those that are ordered alphabetically by title. Quotes in text consign to author and year with the letter.

 Leff, Enrique. 1994b. Ecología y capitalismo. México: Editorial Siglo XXI.
 (Leff 1994a, 113)

Chronologic order to repeated names in a references list.

When the author(s), translator(s), editor(s), or compiler(s) are repeated in several entries in a row, the name (names) is replaced by a line after the first occurrence. The punctuation mark that usually follows the skipped element (here, the point) is not written after the line. Entries are arranged chronologically by year of publication in ascending order, not literate by title. No dated articles (marked as n. d. or s. f.) or in press go after the articles dated.
