Further to last month’s indexing news,
we have been informed that a further four BioMed Central journals have now also been
accepted for tracking by Thomson Reuters and are on course to receive Impact
Factors.

The journals are:

• Journal
  of the International Society of Sports Nutrition
• Particle & Fibre
  Toxicology
• Theoretical Biology & Medical Modelling

which are due to receive Impact Factors in June 2010, and

• Molecular
  Neurodegeneration

which is due to receive its first Impact Factor in June 2011.

We would like to
congratulate the Editors and editorial teams responsible for each of these journals on their success in building the quality and reputation of their journal.

Molecular Neurodegeneration
and Particle &
Fibre Toxicology already have impressive unofficial impact factors of 4.00
and 5.11 (calculated using data from the Science Citation Index ), which certainly bodes well for the future.
