Hodge originally conjectured that every Hodge class in the integral cohomology of a smooth complex projective variety is algebraic, meaning the class of a Z-linear combination of subvarieties. This is false in general. We discuss recent positive and negative results on the integral Hodge conjecture for 3-folds.
