Some information is available from the start, while other articles require you to actually pay to be able to read stuff. Your mail is constantly spammed with letters that your name is mentioned in various papers when it really isn't. Knowledge should be free and accessible to anyone, right?
Hi Bill,
Sorry for the confusion on this! Everything we have to read on Academia is free to download. Sometimes users upload only partial documents, in which case, all we have to offer is the partial document. We wish that everyone would always upload the complete work, but that doesn't always happen!
We try our hardest to find matching Mentions for you, and we're working on making that system better. That's why we offer a 30 day refund guarantee if you feel unsatisfied with our Academia Premium service.
Shoot us an email if you have any other questions!
