Thanks for a great discussion this morning! I mentioned that I would find some resources about the recent LC policy to remove $v from subject authority records. Much of what I have seen is scattered across multiple mailing list discussions, but here is the
official policy (pdf) from LC. They state at the bottom of the document, "There is no requirement for any institution to follow the Library’s practice of not using $v." However, as we discussed, their policy will have a ripple effect depending on how other
organizations (like OCLC) choose to implement it.
