I’m cataloging a novel and find that in the author’s authority record, there is an 053 _4 with a $5 and an institution’s NUC symbol that is not DLC. Does this mean that this institution input this 053 based on their own shelflist without having it approved by LC? Should I propose a number to LC through the usual means and then replace this 053 _4 with a standard 053 _0? I don’t recall seeing this situation before.
