You need to install notefolio to your TI-89.

You can download the program from:
http://education.ti.com/educationportal/sites/US/productDetail/us_notefolio_89.html

After you download the program file, you can use TI-Connect to transfer the program file to your calculator (after you connect the calculator to the computer with the USB cable). To transfer the files, simply drag and drop the program file onto the TI-Connect icon on your computer.

To learn more about the Notefolio app, here is the guidebook:

Unzip it. Transfer it to a Secure Digital card, then plug the card in the SD-card slot. Use the File Manager/explorer and move the library to the Memory location you want.
