Yoga can be found/has mentions in many areas throughout the LC system. As with many works, one can find this topic in just about any call number, for example it could be found in the P's (language/literature) if there is a novel about yoga, or in R under pregnancy as in yoga for pregnancy. Therefore, I am not going to account for every occurrence of yoga. I am going to focus on those call numbers that are most relevant to yoga as a practice and how it relates to religion, psychology, and medicine/health/kinesiology.
