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.
Do one of the following:-
Choose Window > Symbol Libraries > [symbol].
-
Choose Open Symbol Library in the Symbols panel
menu, and choose a library from the list that appears.
-
Click the Symbols Library Menu button on the Symbols
panel, and choose a library from the list that appears.

To automatically open a library when
you start Illustrator, choose Persistent from the library’s panel
menu.
A symbol is automatically added to the
Symbols panel whenever you use it in a document.
Click a symbol in a library.
-
Add
the symbols you want in the library to the Symbols panel, and delete
any symbols you don’t want.

To select all symbols that aren’t used
in a document, choose Select All Unused from the Symbols panel menu.
- Choose Save Symbol Library from the Symbols panel menu.
- Save the new library to the default Symbols folder. The
library name will automatically appear in the Symbol Libraries submenu
and the Open Symbol Library submenu.
If you save the library to a different folder, you can
open it by choosing Open Symbol Library > Other Library
from the Symbols panel menu. Once you open it using this process,
it will appear in the Symbol Libraries submenu with the other libraries.
-
Choose Window >
Symbol Libraries > Other Library or choose Open Symbol Library >
Other Library from the Symbols panel menu.
- Select the file from which you want to import symbols,
and click Open.
The symbols appear in a symbol library panel (not the Symbols
panel).
