Here is the link to install the application (Note that you must use Internet Explorer
for this installation process). Before you install you need to make an empty folder
in your C: drive called "export" (without the quotes). The installer will not function
properly if you don't do that first.
Once you have made the export folder, open this link in IE
and click on Install. It will take a minute and you'll see a "verifying..." window
while it's working. When the install is finished the app will launch. In the future
you can launch it from the Start Menu Programs List under Yale University Library.
The app is quite simple and intuitive - you simply load your two lists as text files
using the Load File 1 and Load File 2 buttons. You'll see the lists appear as you
load them just below the buttons along with a row count. In the boxes below your
lists you'll see any duplicates that have been found in the individual lists. In
the first box to the right you'll see any items from File 1 that are not in File
2 and in the furthest right-hand box you'll see any items from File 2 that don't
appear in File 1. All of those lists can be exported as a text file with the associated
Export button which opens the list in Notetab.
