Ever found yourself browsing the Stacks project and encountering a citation? I did, and I found it quite annoying that I couldn't get any information, unless I opened the bibliography file and started looking for the reference. Not really user-friendly... So I decided to implement an online bibliography :).
At some point this will be improved, parsing arXiv links, making things more consistent, giving overviews per author (maybe), etc. But for now everything is quite workable I hope.
