The U.S. Geological Survey's Publications Warehouse (pubs.usgs.gov) will
complete a process to migrate all of its' on-line publications into
Portable Document Format (PDF) files by September 1, 2011. At that time,
the USGS will no longer support the previous DJVU format for its on-line
publications. Libraries and Web site managers should link to the
publications citation page for USGS publications. At sometime after
September 1, 2011, direct links to DJVU files will stop working and
there will be no automatic redirect to the PDF version of those materials.

A direct link to a USGS DVJU file currently looks
like:***_http://pubs.er.usgs.gov/djvu/B/bull_1967.djvu_*
Once loaded in PDF, individual publications will have a link like this:
*_http://pubs.usgs.gov/bul/1967/report.pdf_*
<http://pubs.usgs.gov/bul/0002/report.pdf>

However, the _preferred_ link to this publication
is:***_http://pubs.er.usgs.gov/publication/b1967_*

The citation link is the preferred link because it may include links to
plates, maps, appendices, etc. as well as links to the USGS Store to
purchase paper copies if they are available. This migration has been
sought by members of the research community for some time. The DJVU
format offered many benefits at a time when bandwidth was a challenge.
The PDF format offers a consistent format for both historical and
current publications and it allows users to download and use information
from USGS publications in the same way that they use research journal
articles and other scientific research products.

Over 70% of all USGS-published reports are available in an on-line
format from the USGS Publications Warehouse. The system currently
includes citations to over 100,000 research articles, reports, and
products produced by the USGS over the last 130 years. The system also
offers an RSS feed to keep users of earth and natural science research
informed about the products of the USGS.
