What are the USGS's plans for the topographic maps?

From the completion of the original 7.5-minute map series in 1992 until late 2008, the USGS mapping program focused on creating national geographic information system (GIS) databases.
 
In November 2008, USGS management committed to design and produce a new digital quadrangle topographic map series, branded as US Topo in 2010. These maps are published as digital documents in PDF. US Topo web site and US Topo FAQs.
 
Topographic maps produced between 1884 and 2006 were originally published as printed paper maps.  More than 179,000 of these maps were recently scanned and published in PDF as historical documents.  Historical Topographic Map Collection (HTMC) web site and HTMC FAQs
