Hi,
There's been a misunderstanding here.
You're showing a structure which is a two-deep hierarchy (Libraries
containing Manpages). That's not what the structure in my example is,
and you're showing something which I think is different to what I'm
asking for. (Or I just can't see how to apply the technique you're
illustrating)
You have to add just another level to my example, nothing more.
...
The structure for my example is Volumes which contain either Libraries
*or* Manpages, and a Library contains Manpages. I'll draw out the tree
from my example again:
(this is the same as in my first email for this thread, but I'm
repeating it here for clarity)
\starttext
   \placecontent[list={Volume,Library,Manpage}]
\startVolume[title=Section 1: Programs]
       \dorecurse{3}{\startManpage[title=progxyz(1)] \input lorem \stopManpage}
   \stopVolume
\startVolume[title=Section 2: Syscalls]
       \dorecurse{3}{\startManpage[title=syscallxyz(1)] \input lorem
\stopManpage}
   \stopVolume
\startVolume[title=Section 3: Libraries]
       \startLibrary[title=libjpeg]
           \dorecurse{3}{\startManpage[title=jpegapi_a(3)] \input
lorem \stopManpage}
       \stopLibrary
       \startLibrary[title=libpng]
           \dorecurse{3}{\startManpage[title=pngapi_a(3)] \input
lorem \stopManpage}
       \stopLibrary
       \startLibrary[title=libbmp]
           \dorecurse{3}{\startManpage[title=bmpapi_a(3)] \input
lorem \stopManpage}
       \stopLibrary
   \stopVolume
\startVolume[title=Section 4: Drivers]
       \dorecurse{3}{\startManpage[title=drvxyz(1)] \input lorem \stopManpage}
   \stopVolume
\startVolume[title=Section 7mk: Makefiles]
       \dorecurse{3}{\startManpage[title=xyz.mk(1)] \input lorem \stopManpage}
   \stopVolume
 \stoptext
Please look at Volume 3; you can see it contains some Libraries
(libjpeg, libpng, libbmp). The other Volumes do not contain Libraries;
they just contain Manpages directly. So the ToC is:
Volume 1: "Programs"       <-- I want a title page for this
   ... manpages for (1)
Volume 2: "Syscalls"       <-- I want a title page for this
   ... manpages for (2)
Volume 3: "Libraries"   <-- no title page for this!! Because this
Volume contains Libraries
   Library "libjpeg"       <-- I want a title page for this
       ... manpages for (3) libjpeg
   Library "libpng"       <-- I want a title page for this
       ... manpages for (3) libpng
  Library "libbmp"       <-- I want a title page for this
       ... manpages for (3) libbmp
Volume 4: "Drivers"       <-- I want a title page for this
   ... manpages for (4)
Volume 7: "Makefiles"       <-- I want a title page for this
   ... manpages for (7)
As I said in my original email, this grouping into libraries only
applies to Volume 3.
The effect I'm trying to achieve is to have a single title page before
each set of manpages. So I want a title page for "Programs",
"Syscalls", "libjpeg", "libpng", "libbmp", "Drivers", and "Makefiles".
But I do not want a title page for Volume 3 itself, "Libraries"
because that would be immediately followed by the title page for
libjpeg, and my aim is to avoid having two consecutive title pages. I
have indicated these with arrows above.
I hope that's clear. Sorry for repeating myself…
Sorry for resending nearly the same example for another time but it still does what you asked for.

\definehead [Volume]  [part]
\definehead [Library] [chapter]
\definehead [Manpage] [section]

\setuphead
  [Volume]
  [placehead=empty,
   after=\directsetup{libraryentries}]

\startsetups[libraryentries]
	\determinelistcharacteristics[Library]
	\ifnum\structurelistsize=0
		\startframed[frame=off,width=\textwidth,height=\dimexpr\textheight-\strutdp\relax,align={middle,lohi}]
			\placeheadtext[Volume]
		\stopframed
	\else
		% Hide the Volume title
	\fi	
\stopsetups

\starttext

\placelist[Volume,Library,Manpage]

\startVolume[title=Section 1: Programs]
  \dorecurse{3}{\startManpage[title=progxyz(1)] \input lorem \stopManpage}
\stopVolume

\startVolume[title=Section 2: Syscalls]
  \dorecurse{3}
    {\startManpage[title=syscallxyz(1)]
     \input lorem
     \stopManpage}
\stopVolume

\startVolume[title=Section 3: Libraries]
  \startLibrary[title=libjpeg]
    \dorecurse{3}
      {\startManpage[title=jpegapi_a(3)]
       \input lorem
       \stopManpage}
  \stopLibrary
  \startLibrary[title=libpng]
    \dorecurse{3}
      {\startManpage[title=pngapi_a(3)]
	   \input lorem
       \stopManpage}
  \stopLibrary
  \startLibrary[title=libbmp]
    \dorecurse{3}
      {\startManpage[title=bmpapi_a(3)]
       \input lorem
       \stopManpage}
  \stopLibrary
\stopVolume

\startVolume[title=Section 4: Drivers]
  \dorecurse{3}{\startManpage[title=drvxyz(1)] \input lorem \stopManpage}
