To find items that interest you, type a word or name into the search box. You can also restrict your search to a particular format, so, for example, if you're just looking for maps, select 'Map' in the Format box.
Then click on the 'Run your search' button.
The system will search all the Item Descriptions for the word or name you entered, and return a list of records (if any are found). You can then click on the 'Reference' on the left side of the list to see all the details about that item.
