Where can I find the billing invoice examples delivered with BIPublisher?

My users want a version of an invoice that can include the open AR Items for the customer so the amount due is more like a statement than just an invoice (carry forward amount). There use to be a sample of each of the delivered invoice formats as a starting point.  I can't find it by searching peoplebooks. I use to have an old 'reports' book on billing tat had the samples but that was Pre BIPublisher.

I'm on Ver 9.2 Pum 32. 

thank you.,
