Archive/categories display full blog

Hi all, When a categorie or archive is selected on my blog, visitors are being linked to a list of (the correct) blogs, but instead of displaying a thumbnail with a small amount of text, the full blogs are being listed. Is there a way to list only a small part of the blogs, like the lay-out of the search results or the main page, when linking from a category or archive? Thanks in advance! Max R ODMGuide.com
