Bibliography

As you gather the sources for your Wikipedia contribution, think about the following:

Is the source from a reliable publication?
- Reliable publications include established newspapers, academic journals and books, textbooks, and other published sources with reputations for accuracy and fact-checking.
- Unreliable sources include blog posts and other self-published works, press releases, and social media posts.
Is the source verifiable?
- In order for a source to be considered verifiable, other editors should be able to consult the source.
Is the source independent of the subject?
- Is the source connected in any way to the subject? This is especially important when writing biographies or about organizations.
- For example, if you were writing a biography, sources like the person's webpage or personal blog would not be considered independent.
Is the source primary or secondary?
- Primary sources include first-hand accounts, autobiographies, and other original content.
- Wikipedia allows limited use of primary sources, but typically only for straightforward, descriptive statements of facts, and only if they are published and verifiable without requiring specialized knowledge.
- Secondary sources should be the main basis for a biography on Wikipedia.
If you're working on a topic related to medicine or psychology, ensure that your sources follow these special guidelines.
If you're creating a new article, consider the following:
- Ensure that your topic meets Wikipedia's notability guidelines.
- In order for a topic to meet the notability requirement, you must be able to identify 2-3 sources that are reliable, verifiable, and independent of the subject you're writing about.
- Finding sufficient sources to establish notability can be especially hard when writing about people or organizations.
- Sources that are not independent of the subject might be useful additions, but don't count towards the notability requirement.
- Wikipedia has developed special guidelines for writing about living persons. Please follow these carefully.
- Wikipedia has a series of guidelines for writing about different categories of people, such as academics and artists. If you're trying to create a new entry about a living person, please look at these carefully.

If you're not sure whether a source is reliable, ask a librarian! If you have questions about Wikipedia's sourcing rules, you can use the Get Help button below to contact your Wikipedia Expert.
