Yorkshire County Council do a good leaflet about using public transport some pages are included above and most of the bus time tables are in the zipped file here.
The bus time tables are zipped, download it and unzip and view locally.
Most bus routes are on it but some you need to follow the links.
The doc is a amalgamation of lots of separate pages from http://www.ukbus.co.uk
and because of this is actually in a invalid format but IE6 doesn't seem to mind.
It is best used by searching for the place name you are interested in.
It contains the year 2003 time tables, see http://www.ukbus.co.uk for other years.
