If you set the cropping to 1/4" on the left and right side of a page in the cropping editor and then apply it to the entire library, it will do exactly what you want. Be aware that it's really only safe to do this if all of your files have a consistent size. If the widths of the pages vary a lot in your library, then the cropping might be not right for a lot of songs.
