How can we edit or add new "Patron category Type" (e.g. Adult, Child, Staff, Professional etc.)

If I remember correctly, these are hard coded in the perl files. Not configurable via admin screens.

Patron categories (/cgi-bin/koha/admin/categorie.pl). Generally speaking your patron categories could all be placed under the "Adult"

That's right. The category types are broad definitions under which your specific patron categories can be created. From the manual-in-progress: 'Category type' is programmed into the system as follows: # Staff = A user that can be configured to perform functions in the staff client # Adult = An average patron (can have child patrons under it) # Child = A patron who must have an adult guarantor # Organization = An organization that can have professional patrons under it # Professional = A patron that can have an organization as a guarantor # Statistical = A "fake" library card. When items are scanned onto a Statistical patron card, the items are not checked out, but recorded. https://sites.google.com/a/liblime.com/koha-manual/Home/Table-of-Contents/ad... Patron categories are the ones you can define yourself: Administration patron category type. It's essentially like a default category. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
