For short summaries and interviews (audio) of new books in philosophy in English. The choice of books is scholarly. You can subscribe to the podcast (for free).
For longer free reviews of recent scholarly books in philosophy see the very voluminous NDPR, Notre Dame Philosophical Reviews (several reviews published per week). These reviews engage philosophically with the texts discussed. You can subscribe to a mailing list.
I often base my decision on what to aquire for the library on these reviews.
