Other than ATReference, does anyone know of any open-source software
designed for tracking reference statistics? I know there are a few
commercial options, but I'd rather stick with open-source. My apologies is
this has already been discussed on here.

Many thanks!
Nathan

P.S. Off-topic, but what do you prefer "open source" or "open-source". I'm
not sure which is most correct.
