Copyright and fair use

In our Avoiding Plagiarism lesson, we gave you tips for citing, quoting, and incorporating various sources into your writing projects. However, depending on what types of sources you use, you may also have to consider copyright and fair use laws. 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.

In this tutorial, you'll learn about the copyright protections that apply to work posted online, including images, text, videos, and more. You'll also learn about the rules that determine which of these resources you can use, and how you can use them.

Watch the video below to learn about copyright, public domain, and fair use.

The laws discussed in this tutorial are United States laws . No lawyer was involved in preparing this tutorial. We are not legal experts, and this tutorial should not be taken as legal advice.

What is copyright?

Copyright is the legal concept that works—art, writing, images, music, and more—belong to the people who create them. According to copyright law, any original content you create and record in a lasting form is your own intellectual property . This means other people can't legally copy your work and pretend it's their own. They can't make money from the things you create either.

You can still cite and refer to other sources (including copyrighted materials) in your work. But to use, copy, or change a copyrighted work, you need permission from the person who holds the copyright. This permission is called a license .

Although everyone has the right to require that others respect their copyright and ask permission to use their work, some people and organizations choose to license their content more freely. They do this by giving their work a Creative Commons license, or by placing their work in the public domain .

Obtaining free content

If everything on the Internet belongs to someone, how do you obtain images, music, and other materials you can use in your projects for free? The answer is through public domain and Creative Commons -licensed content. To learn more, review the tips below.

Tip #1: Use public domain content

There are no restrictions on using works that are in the public domain , which means you can use them however you want—short of claiming that you created them yourself. Unfortunately, it's not always easy to tell whether or not something is in the public domain. There may be some cases when you know for sure that a work is public domain (for instance, if you find a photo or text you are sure was published before 1923), but for the most part the best way to find public domain content is to search for it specifically.

• Prelinger Archives
• PublicPhoto.org
  
• U.S. Government Photos and Images

Tip #2: Use Creative Commons content

Although Creative Commons content won't cost you any money to obtain, it's not totally free: To use it, you must follow certain rules . People who choose to make their content Creative Commons can choose one or more of these licenses to apply to their work:

• Attribution : You must credit the creator in order to use, copy, or share the content.
• Non-Commercial : You can't make a profit from the content.
• No Derivative Works : You can't change the content.
• Share Alike : You can change the content, but you have to let other people use your new work with the same license as the original. You can't treat any Share Alike work that you adapt as your own copyright, even if you radically change it.

For help finding Creative Commons content , try these resources:

• Wikimedia Commons
• Flickr: Creative Commons
• Creative Commons Search

How to tell if content is Creative Commons

To tell if a piece of content is Creative Commons, look for the Creative Commons symbol , as well as symbols that indicate exactly which licenses apply to it.

For instance, the symbols in the example below indicate that the photo has three licenses: Attribution , Non Commercial , and No Derivative Works . This means you can use this photo if you credit the person who created it, don't make money from it, and don't change it.

Finding content with Google

Google allows you to filter your search results to only show Creative Commons and public domain works. When conducting an advanced search, you can choose which usage rights you want Google to search for. For example, if you're searching for an image to use in your blog, you can change the usage rights to free to use or share .

For more information on conducting an advanced search, review the Advanced Search Strategies portion of our Google Search Tips lesson.

Using copyrighted material

As you learned earlier, you generally need to license copyrighted material in order to use it, which often costs money. The exception to this is a rule called fair use . Fair use means you can use copyrighted material without a license only for certain purposes . These include:

• Commentary
• Criticism
• Reporting
• Research
• Teaching

You can't just grab a copyrighted photo and use it on your blog because you think it's pretty. However, it probably would be considered fair use if you included the photo in a blog post that commented on and analyzed the photographer's work.

Guidelines for fair use:

• A majority of the content you create must be your own.
  To return to the example above, it's probably fair use to include a few relevant photos to support your ideas in a blog post, presentation, or research paper. However, using these same photos in a project with only a few lines of commentary might not be fair use. As another example, let's imagine you found a useful tutorial you wanted to feature on your blog. Including one tip from the tutorial would be fair use. Simply republishing the entire tutorial would not be fair use, even if you linked to the original source.
• Give credit to the copyright holder.
  In order for something to be fair use, you must give full credit to the person who created it. This includes the creator's name, as well as other information that will help people find the original work or source. For example, if you adapt a recipe that was originally published on a cooking website, you should include a link to the original page. For more help citing your sources, review Avoiding Plagiarism .
• Don't make money off of the copyrighted work.
  In general, it's much easier to claim fair use when you're using the copyrighted material for noncommercial purposes. While posting images of your favorite TV shows and adding funny captions and commentary might be considered fair use, selling these images on T-shirts would not.

Misusing copyrighted material

Licensing copyrighted content

If you want to use copyrighted content in a way that doesn't fall under fair use, you'll have to license it in order to get permission to post it. If you're interested in purchasing the rights to use images, video, and other media in your work, you may want to visit the following stock photo sites:

• iStockphoto
  
• Photos.com
  
• Adobe Stock
  

Sharing copyrighted videos

Video-sharing sites like YouTube and Vimeo offer the option to share videos by embedding them. When you embed a video, it automatically creates a link back to the place where it was originally posted. Because the original creator or poster is automatically credited, you don't have to worry about going through any extra steps to give credit.

Be aware that many videos on these sites—particularly videos of TV shows and movies—are in violation of copyright law, and may be removed from YouTube at any time. If a video is removed from YouTube, it will also be removed from wherever you've embedded it. You should never embed a video that you know is breaking copyright laws.

Protecting your intellectual property

Copyright protects the things you create too. You own the original content you post on your blog, share on your website, or write in your research paper. If people copy or steal your intellectual property, you have the right to try and stop them.

Guarding your content online

The best way to protect your content is to keep an eye out for it elsewhere. These tips can help you determine if someone else has published your work online, like on a website or blog.

• Use plagiarism search services.
  If you choose to publish your work online, these services will analyze your blog or site, then search for sites with identical content. Copyscape.com is a reputable site with a free plagiarism search.
• Set up Google Alerts for excerpts of your work.
  Google Alerts is a service you can use to automatically email you when sites post new information about a person, thing, or event. You can create alerts for things you've written by entering a few sentences from your work in the Search Query field. (Make sure to use quotation marks .) If that text shows up elsewhere on the Web, you'll receive an email.

• Add watermarks to your images.
  A watermark is something you add to an image to identify yourself as its creator—usually a symbol or some text. If you choose to share your images online, watermarks make it easy for you and other people to recognize images you created. They also can have the effect of discouraging others from taking your images in the first place. You can easily create watermarks in image-editing programs like Picasa and Photoshop .

What to do if you find your content on another site

There are two things you can do if you find your images, text, or other media on someone else's website or blog. First, you can contact the person who runs the blog or site that took your content. Most blogs list a contact email address , but if you can't find one you can always leave a comment on the offending post. Ask firmly but politely to remove your content (or give you credit if you don't mind sharing it). This can work, especially in cases when the other person didn't realize any wrongdoing had occurred.

If contacting the blogger doesn't work, you may want to file a DMCA takedown request . DMCA refers to the Digital Millenium Copyright Act , a law that's designed to help copyright holders protect their content. Under this law, if a site steals your original content you can complain to that site's service provider . If the service provider finds your complaint valid, it will take down the content.
