Throughout the library system there are a number of areas where you can search through the various databases using the Find/Finders window. This window is generally accessed by selecting the magnifying glass icon though there are other buttons that may cause it to appear.
Enter a search term into the 'Quick Search' box and then press Enter on your keyboard or select the green arrow. It is possible to search a number of search fields, these will vary depending on the table you are searching in.
Some of the Find windows will allow you to select more than one resource, click on the record(s) you need and then press 'Select' to complete the action.
