Reaching 2.8 million entries in ZMATH
With quite a headstart into 2009, ZMATH has by now more than 30000 new items indexed during less than three months, which results in an estimation of more than 130000 research articles on a yearly basis! Even on a relative basis, this would be one of the biggest leaps in publication numbers since the beginning of the database count in 1868.On the way, ZMATH passed the number of 2.8 million entries when finishing the daily index run on Saturday morning. The article attached to this little jubilee is
“L1 stability of spatially periodic solutions in relativistic gas dynamics” by Daniela Calvo, Rinaldo M. Colombo and Hermano Frid [Commun. Math. Phys. 284, No. 2, 509-535 (2008; Zbl pre05530498)].
