Message from Calibre below:

We are writing to inform you that Calibre Audio Library’s cassette service is to close at the end of June 2015.

We have maintained this service for as long as possible but we would like to take this opportunity to explain this decision. We found we were unable to replace or maintain the duplication equipment needed for a cassette service. Neither was it feasible to replace or recycle cassettes as each time this process occurs the audio quality deteriorates.
