Using the Catalogue
Finding books is a two step process:
The community structure of the Great Lakes has been impacted by alien invaders. Define the problem. Give examples.
1. Enter alien invasions in the search box to find items with these words together in the same field (i.e. both words in the title, or both words in the same subject heading, etc.)
2. There are only two books from this search. There must be more!
