The ACL Anthology Reference Corpus made up of papers from Digital Archive of Research Papers in Computational Linguistics is now almost twice as large. The corpus is freely accessible even without a Sketch Engine account.

We added texts from the period of 2008–2015 and so extended the corpus to 62 million words. This corpus may serve as a good source for studying academic texts from the Natural Language Processing (NLP) field. You can also carry out a diachronic analysis of the texts.
