How can I edit a composer name?

[Town explorer]

I want to submitt some of Johann Georg Busch's works.
But his composer page is already exsisting as a name "J.G.Busch(fl.1854)".
I want to edit it into excact name,and add birth date,death date,and some additional informations.
How can I edit composer name?

I am afraid you have to create the page with the right composer names, add all existing works and request the deletion of the present work pages.

Thank you. Is it that the name of an existing composer page is not changeable? I see. I will create a new composer page.

You can't change the category https://imslp.org/wiki/Category:Busch,_J.G. But you can edit the present page and add one or more |Alternate Names. See e.g. https://imslp.org/wiki/Category:Fodor%2C_Carel_Anton

Thank you. I think I would better edit the present page and add his full name as an alternative name.
