Libros de la SEP is a free Android app developed by Apps Coronado. It falls under the Social & Communication category. This app allows you to access all the textbooks published by the Comisión Nacional de los Libros de Texto Gratuitos (CONALITEG), which is a public organization under the Secretaria de Educación Pública (SEP) of Mexico. The app has a forum section where you can request help and create your own thread. Additionally, the app features a chat section where users can help each other with their homework or discuss specific topics. The app includes textbooks for primary education, indigenous education, secondary education, and telesecondary education.

The Comisión Nacional de los Libros de Texto Gratuitos (CONALITEG) was created in 1959 by decree of the then-president of Mexico, Adolfo López Mateos, to provide free textbooks to students enrolled in the national education system. The organization's first president was Martín Luis Guzmán, and its first secretary-general was Miguel Ángel Menéndez Reyes. The organization has since transformed into a public decentralized body and now publishes textbooks for various levels of education. The app is a great resource for students who want to access these textbooks on their mobile devices and get help from their peers.
