A good rule of thumb is to recall the acronym TASL, which stands for Title, Author, Source, and License.
Title – What is the name of the material? Provide the title of the work you are adopting.
Author (Creator) – Who owns the material? Provide the name(s) of the author(s) or other creator(s) of the material. Sometimes, the licensor may want you to give credit to some other entity, like a company or pseudonym. In those cases, please just do what they request. Also, if the author/creator has a webpage, link to their page.
Source – Where did you get the material? Link the title to the original source(s). If a hyperlink is not available, describe where you got the work.
License – How can the work be used? Please provide the exact name of the Creative Commons license This link opens in a new window under which the work was released and hyperlink the license name to the license deed page. You can use the acronyms instead of full name of the license.
