To be honest, validating bibliographies does not cost valuable time. Every research group will have their own bibtex file to which every paper the group ever cited is added.

Typically when you add it you get the info from another paper or copy the bibtex entry from Google scholar, but it's really at most 10 minutes work, more likely 2-5. Every paper might have 5-10 new entries in the bibliography, so that's 1 hour or less of work?
