[Esip-preserve] A Note on Data Citations to Support Verification or Replication Scenarios

[Ruth Duerr]

Hi Bruce,

I agree.  There are multiple reasons for citations and we don't have good solutions for all of them.  Credit does seem to be much easier than replication.  But then, I think many scientists would say that results verification should actually use different data and/or different methods.
