A few months ago I got a chance to investigate and find out how to download free audio books legally with a free trial. At the end of this video, I will provide to you a link which will allow you to download free audio books legally.
In my research I come to know that some audio libraries allow downloading books on audios on trial for a limited time period and these trial books automatically expire after the specified time period and do not play.
When you would try to download trial books from the Internet, the resource would only let you download when you would accept their terms and conditions. One should always read the terms and conditions of the resources carefully and should only accept them if they agree otherwise legal problems may arise.
You should follow the rules and regulations of the resource because the resource keeps the right of taking legal action against you if you go against their rules.
