I am currently updating the East Yorkshire Folk Club page of the Yorkshire Folk Arts Directory at http://www.yorkshire-folk-arts.com/directory/clubs_east.html
If your club isn't included you can find an entry form at http://www.yorkshire-folk-arts.com/directory/form.html (It is of course free)
Any venue presenting folk / roots / acoustic music on a regular basis, be it guest nights, singarounds, open mic etc. is eligible but not musician's sessions which have a page of their own.
All the best
