Plagiarism, on the other hand, is when someone passes off another person's work as their own or without recognizing the original source. These tips can help you determine if someone else has posted your work online, for example, on a website or blog. For example, if you want to use someone else's photo or song in one of your own projects, you'll need to make sure you have the legal right to do so. Because the original author or poster is automatically credited, you don't have to worry about taking any extra steps to grant it.
In some cases, you might know for sure that a work is in the public domain (for example, if you find a photo or text, you're sure it was published before 1992), but in most cases the best way to find public domain content is to search for it specifically. When you embed a video, a link is automatically created to where it was originally posted.
