    "abstract": "An introduction is given to an algebraic formulation and generalisation of\nthe consistent histories approach to quantum theory. The main technical tool in\nthis theory is an orthoalgebra of history propositions that serves as a\ngeneralised temporal analogue of the lattice of propositions of standard\nquantum logic. Particular emphasis is placed on those cases in which the\nhistory propositions can be represented by projection operators in a Hilbert\nspace, and on the associated concept of a `history group\u0027.",
