That will be better Bob and I'd like to give some more information on 
that project.

Project went live on 2014 April. All public libraries were using another 
LIS before and it was distributed.
With that project, all libraries started to use a central Koha system 
located on Ankara, capital of Turkey.

It was a derived version of Koha 2.x (co called TG distribution) but we 
implemented many new modules on it.
Therefore we can say a quite derived version of Koha 2.x.  Because of 
distributed system data were very dirty,
there were hundreds of biblios of a single book. Hence we wrote two 
modules to handle them and we merged more than
4.000.000 biblios with the better one, automatically. There is a Catalog 
Center for public libraries now, and they also merge dirty biblios
with the better one. They also create original biblios. This will yield 
the biggest Turkish catalog center.

For the moment, we try to migrate to newest version 3.20.x and tests 
started on that. I think it will go live in 2-3 months.
We will also implement all modules to the new version that we originally 
developed (There are many, some are related with
local solutions).

Maybe, it will be nice to talk about infrastructure.
There is one Load balancer, 4 web servers, 4 clustered databases 
(MariaDB), 1 specific server for ID cards, barcodes, labels.
We do not only implement and serve to Koha project, we also manage those 
servers' databases, web servers, performance issues, etc.

I'd like to share some interested statistics, too.

More than 6.000.000 books circulated in 18 months, there is a record of 
more than 30.000 circulation for a single day.
In average, 2.000 borrowers are being added to system each day but we 
saw app. 4.500 new borrowers last Saturday.

Koha is everywhere in Turkey with that project, even in some small 
villages. Ministry of Culture has some trucks with books and
they travel around the Turkey and circulate books.

If you have any other question I will be happy to share.
I'm planning to join next Koha Conf, and if I would have a chance I want 
to share this project with all of you.
