I write "Where can I find" in the question bar, and a lot of questions come up. Nearly all of them should be offtopic. Yet nearly all of them appear to have good value to aviation.
I can understand why something that can be easily googled may not be appreciated on SE, but if you want reliable, authentic sources, google may not always do it.
And when people ask for resource location on safety material, it seems to me that they should get a better answer than "closed as off-topic". This is, after all, aviation.
