Thank you! I think the Collections template could be perfect, if I can use it on top of the other collections columns I already use?

Yes, you can use template-based collections with column-based collections.

If it's easiest, I could use the publisher name for the collection and change the books I have marked manually, but I would like to keep the collections I already was using if I can.

One publisher name is "BEL Editions" and the collection name is "BEL", and another one is "Bibebook" and the collection is "dp". Would the template look like this?

program:
	str_in_list('BEL Editions, Bibebook', ',', $BEL, $dp, '')

Or do I need to make one rule per collection?

program:
	str_in_list('BEL Editions', ',', $BEL, '')
        str_in_list('Bibebook', ',', $dp, '')

You need a "rule" per publisher. For me, the clearest and easiest way is this:

program:
	switch_if(
		$publisher == 'BEL Editions', 'BEL',
		$publisher == 'Bibebook', 'dp',
		$publisher == 'Baen', 'Baen',
		$publisher == 'Tom Doherty Associates', 'TOR',
		'')

Notes:

• You can have as many "rules" as you want.
• The equals comparison is case insensitive.
• The '' at the end is the default if no comparison matches. You might want to use an actual value there.
• Having a collection name appear twice, for example in both a column and in the template result, isn't a problem.
