'H,' or the Holiness Code, was first recognized as a short body of Kohanite legal texts beginning in Leviticus 19. Israel Knohl, however, argues in his book, The Sanctuary of Silence, for a much more extensive source placed chronologically after 'P.' The 'H' layer popularized Kohanite law for the masses after the Temple was destroyed, and functioned as an intermediary between Kohanite lists and laws and the surrounding narrative. 'H' mainly features in Exodus-Joshua, and is confined in the Book of Genesis to just a few verses in Parashat Toldot.
