The catalog's list of products is nice, but I want to change it to do <something else>.

While the catalog has a lot of features like hierarchical navigation and sortable columns, sometimes you want it to do something else. Or something new. Or just differently. Fortunately, there is a Drupal module that has long been the de facto method of displaying lists of content.

Views.

At its heart, Views is a query builder. By giving it all the parameters through its administration forms, it tracks down all the information it needs in the Drupal database to show you exactly which nodes you wanted. Any information that can be tracked back to the node table in some way can be utilized by Views.
