Excellent observation which just goes to prove that fresh eyes will see things that tired old ones have missed for years I think you are correct that the items actually cited in the text belong with the other references but it is certainly inconsistent with most other Wikipedia articles to put works by the subject of the article into a Further reading section The usual thing is to have a section titled Writings or Publications or sometimes Bibliography though in my view this is confusing since a bibliography normally is a list of references and in articles on composers it is usually placed just before the list of compositions This article as it stands does not represent standard practice and should be changed in my opinion
