Here's a couple of filenames:
0262083558.The.MIT.Press.Ham.Radios.Technical.Cult ure.Dec.2006.pdf
0520233085.University.of.California.Press.The.Hors e.and.Jockey.from.Artemision.A.Bronze.Equestrian.M onument.of.the.Hellenistic.Period.Jul.2004.pdf
041530329X.Routledge.Politics.The.Basics.Jul.2004. pdf

Mostly academic titles, all from the same source.

Many thanks to whoever can lend a hand.

Try this:

(?P<isbn>.+?)\.(?P<title>.+)

You can't easily get a correct title or publisher given the format in the filenames. Just let it overwrite during a bulk metadata fetch.
