Go to the Library, Market St. entrance, and climb the stairs to the 1st floor. Take a right and walk down the corridor to the room that has Local Studies jutting out at you. Go inside this room and look in the bookcase that is on the right hand side wall to you. In this bookcase you will find many small books, well i say books but they are more like, erm, pamphlets. Pamphlet is perhaps not quite the word - 'pamphlets with attitude' perhaps, or 'pamphlets *now with added girth*'. Either way, they are by a chap called Roy Lewis, and are his Stafford Street Series.
I kind of got carried away with the word 'pamphlet' there, in a way that i hope at least some people may find understandable. Bottom line is, go to the library (1st floor) and read the 'Stafford Street Series' - it will tell you all you need to know.
And quite possibly more.
