[Koha] Circulation and no barcode in library

Hello All, I have installed koha 16.11 with the update and am using ubuntu 14.0, the library that i have installed koha on,do not have access to barcode reader or scanners and hence it has become a problem, because when checking out a book to a patron,you need to input the barcode number,likewise when checking in. Please is there a way that i can setup the circulation process to not use barcode but instead the titles of the books to do circulation management. thanks and expecting a favourable response form the community. -- Hughes Dimka Hopewell Solutions Services Nigeria Ltd No.15 Adekunle Kuye Street, Off Agbonyin Street, Off Adelabu Street, Surulere,Lagos State Nigeria tel: +2348066951910 email: hdimka@gmail.com
