Our school uses barcodes for books

In the EduPage "Library" module, you can enter a barcode for a specific title and for individual copies of that title.

The barcode for the book title can be entered in the "Books" section.
In the row of the specific title, click "Edit" and enter the barcode.

The barcode for an individual copy of the title is also entered in the "Books" section.
In the row of the specific title, click on "Items."
In the row of the specific copy, click "Edit."

Enter the barcode for the book copy and save.

Done.
The barcodes have been entered.
