University Archives web archive collection derivatives

The derivatives were created with the Archives Unleashed Toolkit and Archives Unleashed Cloud. The cul-1914-parquet.tar.gz derivatives are in the Apache Parquet format, which is a columnar storage format.

These derivatives are generally small enough to work with on your local machine, and can be easily converted to Pandas DataFrames. See this notebook for examples.
