"Across the case studies we identified three broad categories for the classification of content, which will be unpacked in greater detail in the following section: 1. Instructional material which contains guidance on operational aspects of terrorist and violent extremist activity. This includes guidance on the manufacture and perpetration of attacks, as well as guides on combat drills, fitness and non-violent activism such as sticker campaigning. 2. Ideological material which is designed to specifically further a violent extremist or terrorist world view. This includes key texts and lectures which provide the theoretical underpinning for a terrorist or violent extremist cause, and which provide explanation around why the world is a certain way. 3. Inspirational material designed to reinforce a violent extremist or terrorist mind-set. This includes a wide range of content which is designed to elicit a reaction or response in the radicalised mind. This includes material intended to provoke hatred towards a particular group of people or promote pride and support for a particular cause. Notably, this category of content is the least well-defined in the existing literature." (Page 7)
