A brother on the previous thread about Shaykh Gibril was asking where he can buy the Shaykh's books from.
www.aqsapublications.com publish a lot of his recent works including the latest on the refutation of Ibn Taymiyyah.
www.islamopedia.co.uk also have a lot of the Shaykh's older works.
Google his name and you'll find various other online stores that sell his books.
I hope this is useful.
