Distributing information on the web generally requires the permission of the copyright holder--usually the original creator. Providing the information we request here will help visitors to this site understand the ways in which they may (legally) use what they find.
If you created this file (and haven't signed away your copyright) then we'd encourage you to select the CC Attribution-NonCommercial-ShareAlike option. You'll retain the copyright to your file and can do as you please with it in the future.
Through this choice you are also explicitly allowing others to reuse that file as long as they give you attribution, and don't use it for commercial purposes.
If the file (or content within it) was created by others you'll need their permission. If it predates 1923 or was created by a U.S federal employee (as part of their job) it is likely in the public domain (and we can all do as we choose with it). The original author may also have explicitly stated how it may be reused (e.g. through a creative commons license). You can describe the licensing/reuse situation in the box above.
Without permission you should not upload the file. There are several options in this case:
- You can contact the original author to get permission.
- You can provide a link to (or a description of how to get) the original material rather than uploading it here.
- You can find a substitute that isn't encumbered by copyright.
- You can create a substitute yourself. Remember, ideas can't be copyrighted, only particular expressions of those ideas. Of course you'll want to give credit the original author.
The Stanford Copyright and Fair Use Center has more good information about copyright as it applies to academic settings.
