|This page in a nutshell: Don't indiscriminately add excessive references to an article in the hope that weight of numbers will prevent it from being deleted.|
Bombardment is the placement of a large number of references in an article in hopes that this will prevent it from ever getting deleted. But is it really safe? If you look at a number of AfD debates over time, you will see a variety of reasons articles get proposed for deletion, reasons going far beyond the lack of notability or references, while pages without references are kept.
Wikipedia's notability guidelines state that a subject is notable if there are multiple reliable sources independent of the subject. This suggests that an article bristling with sources should be safe. However, not all sources are equally valuable. A source may be reliable, but only cover a subject in a trivial manner, and if a subject is covered only by trivial mentions then it may not be notable no matter how many of them there are (see WP:BASIC).
For example, single events may be given bursts of news coverage in hundreds of newspapers around the world, prompting hundreds of news articles published on a single day. From the next day, not a single news source can be found.
What is and is not bombardment
Adding additional references is good when each source has a lot of information of its own. Since one of the purposes of references is to provide the reader information beyond what the Wikipedia article says, providing more sources of information is a good thing. Use of the same source to verify different information in different parts of an article may be necessary. But when this occurs, it is still a single source. It may also be useful to provide multiple URLs leading to the same source in the event that one becomes a dead link one day, that the other can back it up.
When the sources are identical to one another or otherwise redundant, on the other hand, this can be seen as bombardment. News agencies like the Associated Press share their stories with many other news organizations. Many news sites then present the exact story, word-for-word. The only difference is the URL used to access the same information. Instead of "multiple, reliable sources," these are merely a single source.
