Hi all,

Does anyone retain superseded BLM maps for any historical purpose? Our past practice has been to withdraw superseded BLM maps, per FDLP weeding/supersession guidelines, but within the past couple of years a decision was made to retain superseded BLM maps of California only for historical purposes. I’d be curious to know if anybody follows a similar local practice, or if anyone has found that superseded BLM maps continue to be useful to your users, researchers, or faculty.

Thank you,

Chris
