		$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.

Brilliant! That's exactly what I need. Thank you very much for your help.
