I'm a Wikipedia editor with over 8000 edits to my name (though I wasn't involved in the deletion of this article). Let me tell you why it was deleted. Danger, Will Robinson: spiel mode engaged!
All Wikipedia articles need to demonstrate notability. They do this through the inclusion of significant coverage - reliable, independent, secondary sources that address the topic directly and in detail, so that you don't need original research to extract content. If you want Wikipedia to have a list of
Thunderbolt locations, you'll need those sources.
Now, you're probably thinking one thing. "What the heck is he talking about?" Therefore, I'll explain what I mean. We'll get to reliability and independence shortly; first, significant coverage.
The definition of significant coverage is fairly broad - the source doesn't need to focus exclusively on the topic, but it needs to be more than a passing mention. So, using the
Thunderbolt as an example, a source that references the
Thunderbolt as "the iconic civil defense siren" before going on to describe fallout shelters is considered a passing mention, while a source entitled "A Complete, Unabridged History of Federal Signal" is probably going to be significant coverage.
Now, about reliability. A reliable source needs to have editorial integrity to allow verifiable evidence of notability. Sources might encompass published works in all forms, in any language. The availability of secondary sources covering the subject is a good test to check for notability. To use the
Thunderbolt example again: how many newspaper articles, magazine features, books, etc., have you seen concerning the
Thunderbolt in general? Not many, I'll bet. How many topics here? The list could go on without end.
Finally, independence. Defining sources that aren't independent is pretty easy. A press release. Advertising. An autobiography. The subject's website. You get the idea. Stay away from things of that nature when you're compiling sources for any article, siren-related or not.
OK, now that we've gotten all the defining taken care of, I'll give you a list of questions to go over.
- Can you find significant coverage of any Thunderbolt in particular? (It doesn't have to be online.)
- Is the significant coverage reliable?
- Is it independent?
- Can you demonstrate that the list isn't simply fancruft that would do better as a sticky here?
If you've answered yes to all of these, congratulations! You've successfully built a strong base to demonstrate the notability of the list.
