Hi! I'm Derrick Coetzee, an administrator on the English Wikipedia (English Wikipedia user page) and Wikimedia Commons. I'm a graduate student in computer science at the University of California, Berkeley in the United States (student homepage) and an amateur photographer. On Commons, I contribute photographs and diagrams and work on image cleanup, batch uploads of public domain images, and automated tools.

I have a bot named User:DcoetzeeBot to perform large automated tasks, and I operate the Wikipedia Mumble server.

For more info about me, see my English Wikipedia user page. When I'm on IRC I'm usually on #wikipedia, #wikimedia-social, #wikipedia-en, #wikipedia-en-admins, #wikimedia-commons, and #vandalism-en-wp and my IRC nick is Dcoetzee.

Scanned works

I've scanned media from a number of books, purchased expressly for this purpose - generally when I upload media from a book I exhaustively scan, process, and upload all public domain media in the book. Following is a link to the category for each one and some samples: Category:Self Portrait: Renaissance to Contemporary Category:Julia Margaret Cameron: 19th Century Photographer of Genius Category:The National Portrait Gallery History of the Kings and Queens of England
