Question: Is the database PASCAL available anywhere as it is no longer available on Dialog?

Answer: Dialog, and other 3rd-party vendors were contractually obligated to remove PASCAL from their platforms.

Institut de l'Information Scientifique et Technique, INIST, (the producers of PASCAL)  ceased updating this database in 2015. 

The only available source of archival data can be found at the INIST website itself:
