Although the passepartout 
				title pages used for the separate issues of the Sieben 
				Lieder eventually (from some time between 1907–11) included 
				a listing of the Kindertotenlieder, the latter song cycle 
				seems always to have been issued with its own title pages
				 
				Each main type is designated by a 
				capital letter, followed by a lower case letter to identify a 
				variant and where necessary by abbreviations in parentheses:
		 
				o = Orchesterausgabe
				k = Klavierausgabe
				u = UE oveprinting
		 
				The title pages used for the 
				collective volumes (with piano and with orchestra) are listed at 
				the end of the sequence.
