Hey thanks a lot for your help.. Works like a charm now.. I'm now learning how to place in a loop and array a specific list of lecturers to be extracted from the code that you've provided me.. I'll post it here if it works right, or yelp for help if it doesn't work right..

The second input file contains data which is similar to savedrecs.txt.. It's because the ISI Web of Science only allows 500 articles per text file so it has to be broken up to two as there are almost 900 articles..
