Listed below are all the USGS series that are currently or
will soon be loaded into the Publication Warehouse. Each series may have
missing report numbers or unverifiable citations.
Missing report numbers are gaps in the numbering
sequence of a series. We do not know if the report was ever released or
if there is a reason why the report number was skipped. These
reports may have been cancelled, recalled, or destroyed. Report numbers
may have been issued in blocks and some may never have been used.
Unverifiable citations are reports that we were
able to find some information on but were unable to verify if that information
is correct or if the report was ever released. Many of the unverifiable
reports were found referenced by other publications as "in press".
