It was just announced that Penguin publishers will be halting distribution of newly-released titles to the Overdrive service, citing security concerns.
Access to all older Penguin ebooks has been restored, however. The 'Get For Kindle' option was also recently removed, but this does not affect Canadian libraries since Kindle versions are not provided through Overdrive currently.
Users who are seeking new Penguin ebooks may not find the materials they are looking for until this issue is resolved. We will make further notifications as news arrives.
