Hi Everyone,

Last month, I sent out a post regarding the expected timing of the Phase 3B NAF cleanup. In that message, our sources were aiming for a mid-November timeframe.

However, it is looking increasingly likely that LC plans to perform the Phase 3B cleanup in early 2016. It appears that LC would prefer to run some more tests in November, wade through the holiday season, then pick things back up again in January for the actual production run.

One other item of note is the addition of ISNI fields in the authority records, as part of the Phase 3B cleanup. Perhaps we all have seen some conversation back and forth on the listservs regarding ISNIs in 024 fields.

The British Library has recommended catalogers to not manually add ISNIs to authorities. Phase 3B will likely remove existing ISNIs and add appropriately validated ISNIs as part of its own process.
