Version 1.0.3 - New option to derive DDC and/or LCC indirectly using Author/Title via OCLC-OWI Identifiers for cases where ISBN/ISSN is not useful or reliable.

Step 1: Derive OCLC-OWI Identifier using Author/Title
Step 2: Derive DDC and/or LCC using OCLC-OWI

Step 1 is unnecessary if you have already attempted to derive DDC/LCC using ISBN/ISSN and had previously configured Library Codes to always add the OCLC-OWI Identifier as a new Identifier (à la ISBN). LC would already have the OCLC-OWI Identifier to use in Step 2.

Bear in mind that the format of the media is implicit in the ISBN/ISSN, whereas it is not at all implicit in a simple Author/Title lookup. For that reason, when doing an Author/Title derivation, Library Codes will always look for the OCLC-OWI with an associated format of "Book", since the DDC/LCC for a "Book" is often very different than for the format of, for example, "Audiobook". Calibre is, after all, first-and-foremost designed to be used for eBooks, although some use Calibre for all kinds of other things in highly creative and complex ways. If you are one of those folks, then you should use ISBN/ISSN for deriving DDC/LCC, and not use Author/Title, unless you want the "Book" DDC/LCC instead of the "Audiobook" DDC/LCC.
