[Koha] how many biblio was modified by each staff

[حسين رضوي]

Hi,

Is there any way to find out how many biblio was modified by each staff of
our library?
We want to get a reports showing to us the biblio and date to each employee
separately.
Mr Bernardo Help me and find something on
http://wiki.koha-community.org/wiki/SQL_Reports_Library#Titles_added_by_catalogerbut
we need to know how many record was edited by each user.

Many thanks
Hussain A.
