 ## Description
@@ -19,6 +20,7 @@ There are been 661 PEPs published.
 The majority of PEPs are published in the Public Domain, but 5 were published under the “Open Publication License” and omitted from this dataset. 
 PEPs are long, highly-polished, and technical in nature and often include code examples paired with their prose.
 PEPs are authored in ReStructured Text; we used [pandoc](https://pandoc.org/) to convert them to plain text.
+This dataset is part of [The Common Pile v0.1: An 8TB Dataset of Public Domain and Openly Licensed Text](https://huggingface.co/papers/2506.05209).
