Pre-1975 JCR data?

[Ackermann, Eric]

Does anyone know if the journal citation data normally found in ISI's Journal Citation Reports is available for pre-1975 years? If my information is correct, the JCR started in 1975. I am doing research that involves the bibliometric analysis of a series of journals from 1968-1972. Unfortunately, I do not have the resources to construct my own journal citation data for that time period. Any help or insight or suggestions provided will be greatly appreciated!

Regards,

Eric
