Hello, welcome to the Fact and Reference Check WikiProject. The purpose of this project is to verify facts in Wikipedia by multiple independent sources, this project works to achieve the goals of the Wikipedia:Verifiability and Wikipedia:No original research official policies. We have some way to go before we attain this goal, but this project will help Wikipedia on its way.
Do you have an article/fact/reference that needs checking? See the Guidelines page for help with tagging articles for review and correction.
Do you need help creating citations? See the Guidelines page for information on how to write references and create citations

Do you have a question? Please feel free to comment on the project Talk page, and someone will try to help as soon as possible!
There are a number of different Wikipedia Backlog categories that help track the existing backlog of referencing activities, they fall into two major groups, Lacking References and Ensuring Accuracy through existing references:
At the moment, there are over 323,545 articles with "Citation needed" statements, they are some of the easiest referencing issues to solve, because you are frequently looking for a targeted and singular reference. You can browse the whole list of these articles at Category:All articles with unsourced statements.
With 323,545 statements that need WP:Verification, sometimes it's hard to choose which article to work on, the tool Citation Hunt makes that easier by suggesting random articles, which you can sort by topical category membership.
