LETRAS (Lima) since 2023 releases articles in "In Press" mode in order to reduce the time between acceptance and online publication of manuscripts, where articles are published online in advance of their appearance in a regular issue of the journal. Articles "In Press" are post-print versions and were approved by the editors. These articles have also undergone copy editing and are published in typeset form after proof-print approval by the author. The only difference between "In Press" articles and those published in a regular issue are some bibliographic data or citation elements: volume, number, pages. However, each article in this section can be cited since they have a unique DOI identifier, in addition to the year of publication, which should be used in all citations made of these articles.

Thematic issue: "400 años after: Guamán Poma de Ayala revisited".   Guest Editors: Rocío Quispe-Agnoli (Michigan State University, USA),  Carlos García-Bedoya M. (Universidad Nacional Mayor de San Marcos, Peru)
