Tardis:Valid sources

When you write an article on our wiki, you need to cite your statements. Knowing which sources are valid is therefore crucial to the writing — and reading! — process. Without a clear sense of what stories will be discussed here — and which will not — your writing may be considered untrustworthy.

Therefore, only valid stories can be used to describe an "in-universe" topic. For instance, if we were writing about Sarah Jane Smith's experience of the country of Italy, we could use anything within The Masque of Mandragora or even The Ghosts of N-Space. But we could not use something from a 1986 fanzine in which Sarah Jane was described as having visited Florence.

For our real world articles — that is, articles about behind the scenes personnel and other things tagged with — it's equally important to know what sources you can use. After all, some girl in South Dakota writing on ilovetennant.blogspot.com shouldn't be considered valid source for our article about David Tennant.
