Over 16,000 sound effects made available for free from BBC library | Information and digital literacy in education via the digital path | Scoop.it
The BBC has made its sound effects archive available to the public for free for the first time. 

The archive incorporates effects used by the corporation's radio output since the 1920s - that tallies up to a staggering 16,000 sound effects.

So you are truly in luck if you're desperately in need of the sound of a South American parrot talking and screeching, the sound of the interior of a Belgian post office (busy, of course), or the sound of an inflating rubber dinghy.
