u mean Utopia by thomas more? its been a while since i read it but essentially more addresses the problems inherent in elizabethan society (esp justice system) through introducing an imaginative island society called 'utopia' which he uses as a device to examine his view of an ideal/improved alternate to europeon society at the time.
Utopia = a combination of greek words meaning 'no place' & 'good place' (ironic) more seems to be hinting that such a place/society is impossible to achieve...
a good place to get info would be the sparknotes website- free and relatively comprehensive (yay!) they have some info on utopia:

* got to remember the context of more heavily influenced the text. it was a responce to society at his time and his values show through the text... e.g portrayal of women & foreigners while progressive for the time is now outdated. the cultural renass. europe was undergoing enabled an intellectual examination of contextual values.
uh, hope that helps
(damn, just realised its too late, o well hope someone finds it useful, this stuff is good background for anyone doing BNW/BR i guess..)
