I have a lot of information on using the NIST Library Search software on HP GC-MS MSD's on my web page. We have found the NIST Version 2 search to be great.

My page includes information on substituting for standard HP PBM search, instructions for using, ways of updating user libraries automatically every night, AMDIS, Wsearch, etc.
