[Dagne Woldie]

Dear all please 

Can anyone direct me to instructions on how to batch delete biblio records . 
I managed to batch delete the items attached to the records and now I need 
to delete the records themselves, but I really don't want to do this one at 
a time for over 1100 records . …Or have I misunderstood the process 
entirely.
