At first I thought it a scam. "First the offer you a free download. If you choose "full package" they ask for your contacts. Then they still offer you the full package, but now you have to buy it. If you now, as you have given away the adresses of your friends, choose only the article you wanted to read the STILL asks for money. Nothing is free here, only lies." But it is only bad programming. It was possible to get the paper I needed about Bernini and the broncedoors of Pantheon and pope VIII.
