When you set up your Livfe collection, you might be wondering exactly what you are sharing in your collection. Essentially, Livfe enables you to share entries in your Papers2 library, which consist of the metadata associated with your entries.
If a PDF is attached to your entry, as would be the case most of the time, the PDF is not shared. At this time we cannot enable PDF sharing with Livfe because of copyright restrictions. By sharing your metadata, other members of your Livfe collection are directed to the publishers website and can download the article (if you are sharing a journal article) themselves.
