Because of the similarity of their order parameters, there are close analogies between defects of /sup 3/He-A and cholesteric liquid crystals. In particular, boojums, originally predicted for /sup 3/He-A, should exist as well as cholesterics. Certain textures experimentally observed and reported in the literature are identified as boojums. A topolgical analysis is given, and the effects of boojums on dynamical properties of cholesterics are discussed.
