The use of tritium-tagged hydrocarbons in analytical research has made it necessary to evaluate some of the parameters involved in liquid scintillation-counting techniques. From these evaluations, a routine procedure for measuring the radioactivity of tritiated organic compounds and the confidence limits of results were established. This paper evaluates the more significant variables and sets forth the conditions and procedure adopted by this laboratory.

-This report discusses five computer-searchable databases located at SLAC which are of interest to particle physicists. These databases assist the user in literature-searching, provide numerical data extracted from papers, and contain information about experiments. We describe the databases briefly, tell how to use the SPIRES database management system to access them interactively, and give several examples of their use.
