[Koha] Koha API

[Edgeworks Creative]

We could use some help understanding how we go about querying the data in
Koha to produce things like book cover images, new item lists, etc.

Is there a good reference you can point me to for understanding how we can
query koha from the website and display results? We (obviously) still
intend to put the koha search itself in place, but I'm talking about
programmatically getting at data.

Any help would be appreciated.
