EndNote requires you to purchase a license for approximately $65. You will own the license forever and can install it on two computers. Our other citation managers are free to you, but if you can get it, EndNote is worth it!
Note for MAC users:
To import, you can select the downloaded file and in Choose Applications, open the EndNote folder and choose the EndNote program icon. You may need to select your EndNote library as well to tell EndNote where to put your citations.
