What’s New In eCO?

Past Updates

June 23, 2025 Release

Two updates have been made to text on the Submit Your Work(s) page of eCO to provide clarity and make the uploading process easier for applicants. First, the instructions for using a zip file have been update to, “If you have a large number of files, please consider compressing them in a zip file for upload. If you do use a zip file, please ensure it is smaller than the 500MB file size limit for uploads.” Second, a link entitled “View Uploaded File Name(s)” has been removed. Applicants will still be able to view the file names of uploaded works directly on the screen.

Additionally, the list of countries for Nation of Publication and Country of Citizenship/Domicile has been updated to remove several U.S. territories: Puerto Rico, United States Virgin Islands, and United States Minor Outlying Islands.
