For instance, it allows for: the rapid development of (sub-)vocabularies; accurate indexes of words and their occurrence in the context of specific works or authors; comparative studies on different literary schools, different authors or different creative periods of a given author; diachronic studies concerned with the evolution of the Portuguese language; among many others.
its unique set of characteristics, namely being composed of complete documents instead of fragments, the carefully edited text, the variety of genres and authors, and the wide time span and orthographic conventions covered, make of it an invaluable and versatile resource for multiple research purposes, both for language technology and digital humanities.
