[Koha] Using Koha without barcodes

Hello! I've been checking out Koha for a customer and it's looking really good so far. The customer isn't using a barcodescanner today though and doesn't seem to want to start using one either. From what I can tell Koha is pretty built around using barcodes? You can't simply lookup a book by name and then directly lend it to a patron by name? Thanks in advance! /Lars
