Field Description
Check Digit: Length The number of digits in the check digit. This field is initially 0. It
changes to 1 if the selected symbology is neither Generic nor FolĆ
lett Classic.
Total length The total number of characters and digits in the barcode, including
the check digit. If you are editing this field, you can only enter the
numbers 4 through 14.
Assigning barcodes
Circulation Plus/Catalog Plus allows you to automatically assign the next
highest available barcode number to an item or a patron. For example, when you
create a patron record, you can either manually assign a barcode by scanning the
number of a physical barcode, or you can let Patron Maintenance automatically
assign a barcode number for you. It does this by finding the highest number that
has been used in your patron barcode symbology and incrementing the item
number by one. If necessary, a check digit is also calculated, but the rest of the
barcode definition remains the same.
Important: Circulation Plus/Catalog Plus use the next highest available barcode,
not the first unused barcode.
Keep the following in mind when allowing Circulation Plus and Catalog Plus to
assign barcode numbers for you:
S Before you assign a barcode, one barcode must already exist that matches
your symbology. For example, if you change your symbology for library
materials to a 14Ćdigit Code 39 Mod 10 symbology, you must first manually
assign a barcode number to an item before the system can automatically
assign a barcode number.
S If you define a nonĆFollett Classic symbology in System Setup, Circulation
Plus and Catalog Plus use the nonĆFollett Classic symbology as the basis for
generating new barcode numbers, not Follett Classic.
S If you assign the highest item number available in your symbology,
Circulation Plus and Catalog Plus cannot automatically assign any more
barcode numbers for you. For example, if you use Follett Classic as your
symbology for library materials, and you assign T 9999999 to an item, you
will no longer be able to automatically assign any more barcode numbers to
library materials.
S While Circulation Plus and Catalog Plus support item number lengths up to
14 characters, the Assign Barcode feature is limited to barcode symbologies
containing item lengths of 9 characters or less. If your symbology includes an
item number length greater than 9, you cannot use the Assign Barcode
feature.
