bibliographic

From protologue citations, to taxon usage citations, to taxon description references, bibliographic data is an essential part of biodiversity data. Currently a number of Drupal applications are using Biblio module (see also Research and Academia Drupal Group) with differing levels of success. I would like to ask what are your experiences managing bibliographic data in Drupal? What use cases, requirements do you have? How could management of bibliographic data be improved?
