Abstract : The principle objectives and goals of the absolute f-value program are delineated in the light of their application to observational astrophysics. The scope of direct measurements is stated in relation to the f-value program. The significant accomplishments achieved in this work are listed and indicate that a considerable amount of knowledge or instrumental potential has been gained regarding f-values, lifetimes, and elemental abundances. Further values of CrI and new values for FeI were measured using the shock tube. Scientific papers detailing the work done are referenced and abstracted. (Author)
