The automatic barcode options define the rules of how the system generates this automatic number.
To alter these settings, log into your library system as a user with administrator level rights (not librarian) and select 'Settings' on the menu bar at the top of the Management page. From the menu select 'Barcodes' and then select the 'Automatic Barcodes' tab.
These settings define how the system generates an automatic barcode number. There are two options that can be specified: Length and Character.
The Length field determines the number of digits the barcode will be when generated. For example, setting the length to 5 will always ensure that the barcode is at least 5 digits, so if the first number were 25, the number generated would be 00025. This is a minimum cap, not a maximum. If you have more records than would allow for 5 digits (when you exceed 100,000 resources), then the automatic barcodes will jump to 6 digits and so on.
The Character field is used to add a letter to the beginning of the barcode. If the length is 5, the character is B and the first generated barcode is 26 then the actual barcode generated will B00026. Notice that the character is not included as part of the specified length and the actual length of the barcode is now 6. If you choose to enter a Character, it must be an upper-case letter.
