Thanks Kovid. I'll look into that approach later. Right now I'm using the title, but I'm not getting very far at all. It doesn't seem my plugin is being called at all. It is loaded successfully, and shows up as a metadata source when downloading metadata, but I see no output from the print statements. My __init__.py is below; can you see what I might be doing wrong?

from calibre.ebooks.metadata.sources.base import Source

class Magazines(Source):

    name = 'Magazines'
    description = _('Download metadata for various magazines')
    version = (0, 1, 0)
    author = 'Graham Wheeler'
    minimum_calibre_version = (0, 9, 0)

    capabilities = frozenset(['identify'])
    touched_fields = frozenset ([
        'comments'
        ])
    has_html_comments = True


    def identify(self, log, result_queue, abort, title=None, authors=None,
                 identifiers={}, timeout=30):

        print 'In identify: %s ' % title
        from calibre_plugins.magazines.worker import Worker

        # Search for results in different thread, as searching takes time and blocks...
        worker = Worker(result_queue, log, title, authors, self, cfg.getOption(cfg.KEY_MAX_DOWNLOADS))
        worker.start()

        while not abort.is_set():
            worker.join(0.2)

            if not worker.is_alive():
                break

        print 'Out of worker: %s' % result_queue.qsize()

        return None
