<li>A bit of work to clean up duplicate DOIs on CGSpace
<ul>
<li>A handful of book chapters, working papers, and journal articles using the wrong DOI</li>
</ul>
</li>
<li>I tried to delete all users who have been inactive since six years ago (July 1, 2018):</li>

<li>I experimented with adding a regular expression to validate DOIs to the submission form
<ul>
<li>It is a slightly modified version of the one found here: <ahref="https://stackoverflow.com/questions/27910/finding-a-doi-in-a-document-or-page">https://stackoverflow.com/questions/27910/finding-a-doi-in-a-document-or-page</a></li>
<li>I decided it will probably be confusing to people and will have limited benefit, since we are normalizing most forms of DOIs to our preferred form after submission anyway</li>
