Symbol libraries are collections of preset symbols. When you open a symbol library, it appears in a new panel (not the Symbols panel).
You select, sort, and view items in a symbol library the same as you do in the Symbols panel. However, you can’t add items to, delete items from, or edit the items in symbol libraries.
