Databases are characterized by format (among other things). These formats (audio, data & statistics, dictionaries & encyclopedias, e-books, government documents, images, maps & GIS, newspapers, and videos are all types that can be associated with a database. Databases may fall under more than one type. Types can be filtered and browsed for easier access.
Resource icons provide a visual representation of the various types of assets available in LibGuides. Databases (as well as other assets) may use multiple icons. These icons can be used and associated with ANY asset although some are restricted for databases and are set by Admins.
