work title question

[David Campbell]

I notice that some work pages include the opus/work numbers in the Work Title field (red box, under General Information) while others do not.

For example:
http://imslp.org/wiki/5_Characteristic_Pictures,_Op.18_(Ippolitov-Ivanov,_Mikhail%29
includes the opus number, while

http://imslp.org/wiki/3_Morceaux_caract ... ues,_Op.47_(Sauret,_%C3%89mile%29
does not.

Are opus, work list, etc. numbers desired in this field? If so, can this be addressed globally or would it be best to adjust these as found? Thanks.

In the red box of the General Information there should generally be no opus/work numbers, they are not regarded as part of the title. Unfortunately they appeared after the uploading process, if the header of the work contains it. One have to correct this by hand.
