I couldn't find any Church House Publishing books in your collection, which leads to the rather odd situation for Church of England Anglicans that you have books about Common Worship (one of the main liturgical resources), but not Common Worship itself. If you want to break into the mainstream market for Anglicans in England, I'd have thought some type of agreement with Church House Publishing would be extremely beneficial to both parties and would enable other electronic devices other than a Kindle (or Kindle app) to be used by those that put together services.
