I use Zotero all the time to manage papers and books. Today I'll be developing a command line interface to Zotero. (There's not already one of these? Really?)
I'll begin sketching out planned functionality while I eat lunch at 12:00 (eastern time), start coding at 1:00 and hope to be finished no later than 2:00. Code will be available at https://github.com/hourchallenge/zot. The final result will be available on the Python Package Index as soon as it's relatively functional.
Update (2:00): my command line client can currently search for articles by title, author, or publication. I'm going to go for another hour to see if I can finish up.
Update (3:00): after two hours, I'm calling this finished. To try it out:
pip install zot
zot path /path/to/your/Zotero/directory/
zot search --author Brown | zot bib
