changing backgrounds

I am new to the gimp and have been working with a scanned sketch. I am attempting to change the background (now white) to a transparent background however I am having difficulty separating the actual sketch from the background. I have searched through gimp tutorials, help and several books as well as the archives however I have not been successful at accomplishing this. If anyone has any suggestions on how I might do this or point me in the right direction for further instruction, I would be most appreciative. Thanks in advance. T

Probably you want to use the Color to Alpha plug-in, and select white. It's at /filters/color/color to alpha.
