2005, Al-Qutaish, R. E.. and Abran, A., An Analysis of the Design and Definitions of Halstead's Metrics.

Some software measures are still not widely used in industry, despite the fact that they were defined many years ago, and some additional insights might be gained by revisiting them today with the benefit of recent lessons learned about how to analyze their design. In this paper we analyze the design and definitions of Halstead's metrics, the set of which is commonly referred to as 'software science'. This analysis is based on a measurement analysis framework defined to structure, compare analyze and provide an understanding of the various measurement approaches presented in the software engineering measurement literature.
