Are 18 citations few or many?
Relative metrics may help.
YCR = Year / Citations / Relative
Relative > 1 is good; more is better.
Relative 0.80-0.99 is good enough.

YCR = 2011 / 35 /  0.98 

YCR = 1989 / 26 /  1.42 

YCR = 2010 / 18 /  0.54 

Scientific articles differ widely in quality and influence. To reveal those differences, we are building a concise suite of performance metrics, first tuned for Oncology and now extended to the broader Biomedical literature. As a non-profit scientometrics initiative focused on relative citation measures, we aim to offer transparent, field-sensitive indicators for researchers worldwide.
