Maps without copyright

For those who worry about copyright issues with the many wonderful maps available on the internet, I know of two good recourses that do not involve delving into the arcana of either the general rules on fair use of maps or a particular source's claims of rights. These are maps produced by the federal government, making good use of our tax dollars:

the National Atlas, and especially the mapmaker part, which deserves an extended discussion in itself but won't get it here; and

the Census Bureau, which has individual state maps of counties in outline, as well as a map of the whole country with counties in outline. That last comes in especially handy when your research targets thoughtfully lived next to the state line. (Thanks to Kathy Lenerz.)

Just because these are not copyrighted does not mean you can claim you made them yourself! Stay calm and cite your source.

Outline maps for counties

The inimitable Bill Bryson ("I come from Des Moines. Somebody had to.") explains how important directions are to Midwesterners.

"Any story related by a Midwesterner will wander off at some point into a thicket of interior monologue along the lines of 'We were staying at a hotel that was eight blocks northeast of the state capitol building. Come to think of it, it was northwest. And I think it was probably more like nine blocks.'" (The Lost Continent, page 15)

In that spirit I was delighted to find Genealogy Miscellanea flagging the National Atlas website as an excellent source of free printable county maps for all states. It reminded me of another, more obscure site offering a variety of free maps: geology.com. For Illinois (and every other state AFAIK), geology.com offers

(1) county outlines (no names or towns) on a physical map of the state,
(2) county outlines with elevations (not much of that in Illinois),
(3) county outlines with major highways,
(4) county outlines with major highways and a good sprinkling of towns,
(5) county outlines and names with lakes and rivers,
(6) county outlines and names in color,
(7) county outlines and names and county seats in color.

Now, can anyone suggest a site that has a township map for each and every county in the US?
