Objective  To analyze the citation of the International Journal of Biologicals and understand the requirement and utilization of literatures by the scientific researchers in the field of biological products.  Methods  Bibliometrics methods were used to analyze the references cited in 159 articles published in the International Journal of Biologicals from 2006 to 2009.  Results  A total of 2998 references were cited in the 159 articles. The average citations per article were 18.86 pieces. The Price Index was 56.00%. Citations from journals and in English- language were 94.83% and 85.96%, respectively. The citations from the high-ranked 20 journals accounted for 35.98% of all citations.  Conclusions  Most citations come from journals and in English language. Although the Price Index is more than 50%, it has decreased gradually during the 4 years and indicates that the authors read recently published articles as much as possible.
