hmmm - let me try to explain, 

So, I am creating a custom website front that display the books stored in KOHA for sale. 

What I am trying to achieve is that:
1. When biblio is created on Koha, it is reflected on my custom website (I can do this through API and cron)
2. If the biblio details updated, it is reflected on my customer website (I can't do crone, as i need instant update)
