Every day, just shy of 1000 new articles are created on Wikipedia. Every day, several hundred are deleted. And the pattern repeats, till we find our place on the path unwinding. But how how is this decided?

In most cases, articles are deleted because they fail the Notability requirement (see week 20), although Wikipedia's deletion policy lists more than a dozen valid reasons for doing so.

Anyone can nominate an article for deletion, but only an administrator can carry it out. And look before you nominate—where possible, editors are supposed to look for alternatives to deletion.

Infrequently, obvious junk like a nonsense page can be put up for "speedy deletion". In most cases, however, articles of dubious merit are nominated for deletion. This creates a listing for it at Wikipedia's Articles for deletion (AfD) project—itself the topic of a future installment.
