The Amplified Bible was first published in 1965 by The Lockman Foundation. Keeping in mind the fact that some of the original language does have one exact translation into English, translators left some passages with alternate endings or added explanations of possible differences. The version published on BibleGateway.com is taken from the 1987 printing.
