How do I log in to OPL online?
If you are receiving a message that your library barcode is not in the system, it's possible that it is an old expired card; they do expire every five years, and are purged from the system after an additional five years if they have no outstanding fines, etc. Or possibly you have mistyped the number? In any case, you can stop in at any Omaha Public Library branch with a photo ID and current proof of address (current driver's license meets all criteria) and they will get you all set up again, including setting (or resetting) a PIN.
I hope this helps! Thanks for using AskOPL.
