3. LOW PRIORITY - Panoply snapshots ncdf11.jpeg through ncdf13.jpeg are fuzzy and should be replaced (in keeping with Panoply usage as described in primer)

8. "As a result, ideally, it would be helpful for the repository to be involved during the research life cycle; otherwise, it would be useful for the repository to be able to interview the researchers, such as by using the Data Curation Profiles, in order to compile the relevant descriptive metadata and information for documentation"; link should be replaced with https://docs.lib.purdue.edu/dcptoolkit/ - the previous URL is captured by scammers
