Beth,
Information about Primary Base Series (PBS) maps is online at
http://www.fs.fed.us/gsc/products.htm
and
http://www.fs.fed.us/gsc/more_pbs.htm
These are U.S. Forest Service (USFS) and not Bureau of Land Management (BLM) maps.
Some information about BLM maps is online at
http://store.ca.blm.gov/webc/webc.cgi/st_main.html
BLM and USFS do work together with geographic data
http://www.blm.gov/nils/
but I haven't seen the phrase "primary base series" used for BLM maps.
HTH ... Charley

Subject: USGS topo question
I hope this isn't too ignorant of a question to ask... I do appreciate any info anyone can give me!
I had a patron yesterday requesting a particular USGS topo quad of the "primary base series". He said these types of maps had been done in the last 15 years showing BLM type information - such as mining claims and ownership - on 7.5" topos. I didn't know this was a series and we didn't have the quad he wanted though he said it had been completed so I'm not sure of the info he provide me. Would there be a list, or would these be noted in a guide somewhere?
Can anyone give me insight to this series? I'd love as little or as much info as you can provide. You can email me directly with responses....
Thanks!
Beth
