Downloads of EVS terminology files have grown to an average of over 100,000 each month.

Number of files downloaded January 2013 - September 2015

Downloads Through HTTP Access to EVS FTP Site

EVS provides an HTTP interface to the FTP site allowing users to download files directly from the web, without the need for using an FTP client, at http://evs.nci.nih.gov/ftp1/.

In June 2014 EVS began publishing disjoint branches of the NCI Thesaurus, allowing NCIt users to select their domain of interest rather than downloading the entire vocabulary.
