Doing a Classification Number Search (Dewey)...
A list of resources that start with the numbers you searched for are displayed in Call No. order... which is basically a shelf list of the resources. It is interesting to scroll down and watch the subject of the resources change as the Classification numbers change... this can be an interesting revelation for students and staff alike.
See Using the Results Screen (Resource Lists) for more details about manipulating the list of resources that appears as a result of your search...
