Perspective on "Principles for a direct SCF approach to LCAO-MO ab initio calculations" - Almlof J, Faegri K Jr, Korsell K (1982) J Comput Chem 3 : 385-399

The direct self-consistent-held (SCF) method recalculates all two-electron integrals each time they are needed in an SCF calculation. This perspective article discusses how the original paper on direct SCF by Almlof et al, de veloped the principles by which this could be made efficient and thereby pr ovided an example of the semantic approach to computational chemistry in wh ich algorithm development and coding are not compartmentalized.
