Any ideas why the second part of this template isn't removing the URIs?

program:
	publisher = $publisher;
	ids = $identifiers;
	u = select(ids, 'uri');
	g = select(ids, 'gutenberg');

	if publisher == 'Project Gutenberg' && u != g then
		n = re(u, '^http://www.gutenberg.org/(\d+)', '\1');
		ids = list_union(ids, strcat('gutenberg:', n), ',')
	fi;

	if publisher == 'Project Gutenberg' && u && g then
		ids = list_difference(ids, strcat('uri:', u), ',')
	fi;
	ids

Are you certain that the conditions in the second 'if' are all True, that both 'ids' are set when the template starts? Run it using breakpoints to check (and record) the values.

Also, both conditions check for "publisher == 'Project Gutenberg'". You could test that once and put the other tests as nested ifs.
