how to enter a book --- I am lost ...

[Joseph Potter]

Hello group.

I have experience with Linux but none with libraries. I have to take a
collection in a small, private, religious school and figure out how to
enter the collection into Koha.

We had in the past a for-pay system but it crashed and all data was
lost. I was not here then. So, I have a large room full of books and
most have a little wand reader stick on but that is all we know.

I have Koha running on a linux server (the 10.4 version) and all looks
OK.

My question is: how do I start entering books into the system?

Thanks.
