Annual Usage Graph (per Month) as provided by EZB Total: 2002=206.328 Total 2007= 185.361 Question: Is there growth ? Why 2002 months so different ? Other years look more like 2007

How to explain Month-to-Month variation ?

EZB e-Journal Service UsageDescribing & Interpreting

Observations Introduction: 2000-2001

Initial usage „Breakout“ Long & Strong Adoption

7 Years of cont. Growth Growth / Annual Change

2000-2006 + 8-12 % p.a. Since 2008 – 3 % 2009 only extrapol.

Small reduction continues (?) Maturation

Plateau Use at Level of 10 Peak reached in 2007: 10,4 ?

Further Service Evolution !?!
