The war on Proverty will probably never be won and this problem shall always be with us. But we should still make every effort to eradicate it. It appears 11 times in OhioLINK and 10 times in my own OPAC, and is a "moderate probability" typo on the Ballard list. "Low probability" versions of poverty and its cognates include Povery, Impovi*, and Improvish* (though whether you regard the latter two as forms of impoverishment or improvisation may depend on your pov). Note that this can occasionally be a misspelling of property as well. In an amusing amalgam of yesterday's and today's typos, an entry in OhioLINK reads: Language and Proverty, by Frederick Williams and Rita Naremore, published by the Institute for Research on Poerty. And then there's this portrait of LBJ on a University of Michigan web page, with its misspelled caption: "President Lyndon B. Johnson, founder of the Head Start Porgram during his War on Poverty."
