National Statistical Offices and Central Banks Web Archive collection derivatives

<p>Web archive derivatives of the&nbsp;<a href="https://archive-it.org/collections/10637">National Statistical Offices and Central Banks Web Archive</a> collection from the <a href="https://archive-it.org/home/IvyPlus">Ivy Plus Libraries Confederation</a>. The derivatives were created with the <a href="https://github.com/archivesunleashed/aut/">Archives Unleashed Toolkit</a> and <a href="https://cloud.archivesunleashed.org/">Archives Unleashed Cloud</a>.</p> <p>The <strong>ivy-10637-parquet.tar.gz</strong> derivatives&nbsp;are&nbsp;in&nbsp;the <a href="https://parquet.apache.org/">Apache&nbsp;Parquet format</a>,&nbsp;which&nbsp;is&nbsp;a <a href="http://en.wikipedia.org/wiki/Column-oriented_DBMS">columnar&nbsp;storage</a> format. These derivatives are generally small enough to work with on your local machine, and can be easily converted to Pandas DataFrames.
