The download option in Web-of-Science were recently (2013) changed. My programs run on downloads saved as “plain text” (under “other file formats” in the “Marked List”) or in the so-called “tagged format.” A title is then indicated with “TI ”, and an author with “AU ”.

 

The downloaded files (of any size) have to be copied-and-pasted together into a single file named “data.txt” that can thereafter serve as input to the various routines. There is often a limit of 1024 variables, but the number of cases (documents) is not limited (below a systems limitation in Win-32 of 2 GB).

 

One is advised to run the routines in a command box from the C-prompt because one receives error messages in that configuration. Large sets may require long processing times.
