 ### Dataset Summary
 
 The SF Nexus Extracted Features dataset contains text and metadata from 137 mid-twentieth century science fiction book covers, originally digitized from Temple University Libraries' Paskow Science Fiction Collection.
+Because this is a collection of copyrighted fiction, the texts in this dataset have been disaggregated.
+Each text has also been split into chunks of approximately 1000 words to improve performance of topic modeling and other NLP analyses.
+The metadata includes information about the texts' title, author, publication date, and (sub)genres. 
+
+### About the SF Nexus Corpus
+The Paskow Science Fiction collection contains primarily materials from post-WWII, especially mass-market works of the New Wave era (often dated to 1964-1980).
+For more information on the project to digitize and curate a corpus of "New Wave" science fiction, see Alex Wermer-Colan's post on the Scholars Studio blog, ["Building a New Wave Science Fiction Corpus."](https://sites.temple.edu/tudsc/2017/12/20/building-new-wave-science-fiction-corpus/).
