I like the idea of having a recommended set of papers.  

As of the original request,  I think it's very important for those who want some custom notes about something, e.g., best paper, also appear in,  etc.   I would think the implementation of this is stratight forward,  Bibbase already supports custom field such as url_link etc.  Hope you can get to do this soon. 

Thanks again for creating Bibbase,  it's quite useful.
