Drupal views contextual filters I have set up a Drupal View (as a block) listing a number of books in my left sidebar (an unformatted list of fields, title, image etc.), in the main area the individual book is displayed as you click on the image in the left sidebar. Is it possible to use the contextual filters to disable that particular book from my view in that left sidebar? 
I'm relatively new to Drupal! Many thanks if anyone can help!
Yes, you can use a contextual filter on a node nid.  For its value, select a default argument (since a block won't have it) and then select node id from url.  Then also click on exclude the argument.  This will create a contextual filter that excludes the node on the page from the View.
