Purpose: The article investigates the correlation between citations and the document supply of print serials. Approach: The study is based on data from INIST-CNRS for document supply requests and from ISI for citations from 89 serials with JCR impact factors in pharmacology. Data were collected from 1992 to 2004. Findings: The results distinguish four groups of serials with different relationships between document supply requests and citations. The characteristics of the serials of the four groups are described (year of creation, price, etc). The evolution of the correlation between document supply and citations is analysed. Originality: This is the second of three articles on a longitudinal study over 13 years on different aspects of the relationship between document supply and impact factor (citations) in pharmacology, a scientific domain with a high use of scientific information.
