La Salute è in voi! ("Health/Salvation is in you!") was an early 1900s bomb-making handbook associated with the Galleanisti, followers of anarchist Luigi Galleani, particularly in the United States.

It wrapped this content in a political manifesto advocating for impoverished workers to overcome their despair and commit to individual, revolutionary acts. American police and historians used the handbook to profile anarchists and imply guilt by possession. It figured prominently in the prosecution of the Bresci Circle, a case that revolved around the anarchists' right to read. Successful political bombers of this era ultimately had career backgrounds in explosives and were not the self-taught amateurs the handbook sought to create. (Full article...)
