Without boring you with too much detail... I try to be thorough with cataloging my collection. I label each individual fossil, and record them in a database that contains all known information about that specimen.
My question is... If I remove a fossil from my collection, how should I label it in my database? Should I leave it alone, mark it somehow as being given away/sold/traded/etc., delete the entry entirely? I realize this is probably more of a personal preference, but I'm curious as to what others do when removing a fossil from their collection records.
