TIGOR - 2006 First Edition TIGER/Line in ESRI Shapefile format!

Hey, its not free but its pretty cheap and may be of interest to you. Product details - TIGOR is an integrated data product that gives you all the layers of the 2006 First Edition TIGER/Line® in ESRI® Shapefile format! TIGOR is based on Census Bureau TIGER/Line® files; TIGER/Line® is a registered trademark of the U.S. Census Bureau. - See http://www.nextractor.com
Of note, beware of free Tiger data that may be for sale dirt cheap on commercial sites (like the data depot, etc...) as it likely may not be reformated and is freely available via ftp download from the US Census Bureau. If its not publicized as being in SHP format then you'll likely simply get native TIGER files which require much effort to use in your GIS

Free USGS DRG data downloads from Libre and the Internet archive... download away!

Remember the USGS DRG map ransom project that "freed" the data, making these data freely available for public download? Well, its been some time and it seems that the data are indeed freely available for all. I surfed around a bit this AM and wanted to remind any of you GIS techs and managers that are STILL paying for these free data to consult this fine resource as an alternative. Data are available from a coulpe of locations and served up via http or ftp download. You can browse by State from the following locations:
http://libremap.org/data/ - the libre map project UI
or
http://www.archive.org/details/maps_usgs - the Internet archive
