I suppose the main point is that we (catalogers and administrators)
should refuse to panic ourselves into a hasty decision.
Let's look at a different set of numbers, drawn from a scan of all
name authority records issued from 2003-2005. In that time, there
were 1,251,147 records, of which 852,890 were coded as 'new.' Of
these new records, 59,648 were coded as series (a, b, c or z in
008/12). Of the headings in these new series authority records, 380
appear as traced series in bibliographic records in Northwestern's
database. (The number seems to me a bit low; I'm re-running the test
and asking the question another way; but so far the results appear to
be the same.) This could be taken to mean that even if Northwestern
were the only PCC participant that decided to continue to create
series authority records, we would need to create only a few
additional new records per week to keep up with the load.
