For Level 2, a typical thing to do is to attach full text documents. So, in this case you can attach the full text pdf documents by clicking the paper clip icon. And then you can browse on your hard drive and find a PDF document to attach. If you originally imported your references from an EndNote library, you may be able to upload all of your documents using a special utility designed for this purpose (contact us at swift-activescreener@sciome.com for more information).
