Abstract: The Garfield (Impact) Factor characterizes the measure of the up 
to date specific contribution of scientific journals to the total impact 
of the journals in a special field. A new indicator (Contemporary 
Contribution Index, CCI) was introduced in order to characterize the 
relative contribution of journals to recent, relevant knowledge of a 
corresponding field. The CC Index relates the number of citations received 
by a journal in a given year to the total number of citations obtained by 
all journals of the corresponding field in that year. Mean Garfield 
Factors and mean Contemporary Contribution Indexes were calculated for 
some fields and several journals. No significant correlation was found 
between the Garfield Factor (GF) and Contemporary Contribution Index (CCI) 
of journals. The ratios of the GF to CCI referring to the corresponding 
top 10, 20 or 50 per cent of the journals ranked by decreasing GF and CCI, 
strongly differ by field.
