Plattsmouth LCCNs

[lweakly]

The LCCNs for the new batch of the Plattsmouth Journal are incorrect.

The LCCN for batch_nbu_plattsmouth04_ver01 are sn 95069723, which is the microfilm lccn, not the print lccn. The print lccn is 2016270206

Before we change this however we need to check with Margaret because there is also an oclc record using the same number, but prepended with sn - we need to confirm which one is correct. If the one with the sn is correct, we will also have to fix the older batches to add the sn.
