Many of the audiovisual resources can be found in Library Search. Use the "Content Type" options to refine your search results.
If the items do not have specific thumbnails you can also look out for content type icons like these:



Look for the "Map it" buttons to see floor plans with locations of items.
Another way to find the online and streaming audiovisual resources is the Electronic Resources list. Search the list by keyword for ‘video’ or ‘audiovisual’, or use the "Content Type" menu to select audiovisual or streaming video. You can choose which resource looks the most useful and then search it directly for content that meets your needs. This will include content which cannot be found in Library Search.
