Hi
The Lancashire Online Parish Clerk project is a wonderful free resource that might help in your research. I know from personal experience that the records on this site are transcribed by volunteers using the microfilm of the original parish registers. The transcriptions are then checked twice before being accepted and uploaded.
Naturally though, this is just a tool to help you find your way back to the original records yourself.
You will find information here:
