But it doesn't...

You have a page for Volume 3 (which is made blank due to your
\ifnum\structurelistsize=0):

>> Volume 3: "Libraries"   <-- no title page for this!!

Instead, I'm trying to find how to not have this produce a page (or
some other way to achieve the same effect).

And you have no title pages for these:

>> 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

Of course these pages would be easy, using just the normal way, if the
page for Volume 3 can be not output somehow. But I don't know if
that's there's another way which I'm not aware of.

I'm trying to separate describing the effect I'm trying to achieve
(where I drew "<--" for each page I'd like to produce) vs. my idea for
implementing that effect (to somehow not produce a page for Volume 3,
and then to produce title pages for each Library), because there are
often surprising ways to do things which aren't what I'd thought of.

Thank you for taking the time with this,
