New Impact Factors announced

Journals published by BioMed Central have again received impact factors
that compare well with equivalent subscription titles, with five titles
in the top five of their specialty.

BMC Bioinformatics
<> , with an
impact factor of 5.42, has reinforced its reputation as one of the top
journals in its field. Launched in 2000, it is the second highest ranked
bioinformatics journal, and already has an impact factor comparable to
that of Bioinformatics (5.74), the most established journal in the
field, which has been publishing for more than two decades and is
supported by a major society.

Critical Care's <>
impact factor jumped from 1.9 to 3.21, and the journal is now third in
the critical care medicine field having leap-frogged the competitor
title Intensive Care Medicine, the official journal of the major
European society. Breast Cancer Research
<>  also increased
it's impact factor from 2.93 to 2.98 and remains the second highest
ranking breast cancer journal. Arthritis Research & Therapy
<>  maintains its
rank of second in the rheumatology field with an impact factor of 4.55.
With an impact factor of 4.03, Respiratory Research
<>  is the fifth
most cited journal in the highly competitive respirology field. 

Other journals published by BioMed Central also received revised impact
factors this year, including: 

BMC Cancer <>  


BMC Cell Biology


BMC Genomics <>  


BMC Health Services Research


BMC Infectious Diseases


BMC Molecular Biology


BMC Musculoskeletal Disorders


BMC Public Health


The impact factors, which are calculated by ISI, look at citations in
2004 of articles published in the journals in the period 2002-2003. The
high impact factors for these journals affirm that they are respected by
researchers, and are fast becoming the place for authors to submit
important research findings. For full details, please read our press
release <>  or
