Im Radio Archive auf archive.org gibt es eine neue Suchmöglichkeit namens “Search radio transcripts” (via datahorde.org):
«The feature does seem to be in a WIP stage, so you might encounter some inaccuracies. Also of note is that only broadcasts from the past 5 years or so are available, from selected collections.
Still, there’s over two million recordings waiting for you to hear their story! You can view the full “catalogue” of radio broadcasts which support this feature in the aptly named Radio Archive collection.»
