Comment 12 for bug 520839

As it stands, pcrud.search by barcode, using the field mapper class acp,
obtains the copy data needed for Item Status display.

There is no field mapper class that includes all of the acp data plus isbn,
and getting the acp data is a must.

So, given isbn, do 2 additional pcrud searches:
1st, by isbn, fm class rmsr, to obtain tcn_value;
2nd, by tcn_value, fm class rocit, to obtain barcode.
And then with that barcode you can do your acp pcrud to get back on track.

I'll be working on a rough draft to fit the additional searches into the copy
retrieval logic.
