Edition column

at least in the 20th century a number of Hansen scores received "Wilhelm Hansen edition" numbers as well- perhaps it is worthwhile including a column for this (especially if there is a risk of anyone confusing this with a plate, though I doubt this - but it might be useful information too anyway) (eg Jørgen Bentzon string quartet op15, copy. 1930 I think, "Wilhelm Hansen ed. No. 3204a.", not sure what the plate no. is at this time...) I believe the publisher had other editions also, so this might require some disambiguation. Eric 13:53, 17 April 2011 (UTC)
