COUNTER-compliant publisher-provided e-journal use statistics are enabling unprecedented ease of computation of journal value metrics like price-per-use. This improved accessibility, however, is likely to increase the prevalence of miscalculation and misinterpretation of value metrics.

It is concluded that recent improvements in the COUNTER standard are providing most of the necessary ingredients for meaningful evaluation—what's needed is critical analysis of and consensus as to the best way to apply these figures.
