Ephemera as past-tense


I’m home sick, but working, stuck trying to finish a small story so I can move on to a huge one, and one procrastination Google led to another led to another, and I ended up on the wikipedia page for Ephemera. It’s a really good example of the contradictions that come up on Wikipedia, where documents are edited by committee, and quickly. First sentence:

Ephemera is transitory written and printed matter not intended to be retained or preserved.

Then, halfway down the page:

The large capacity and reach provided by resources such as the Internet Archive and YouTube have made finding and sharing video ephemera (past and present) dramatically easier.

No one has come in and added anything to explain how the second sentence does not stand in violation of the first—that is, how it can be that ephemera could be preserved in an archive/online database and not cease to function as ephemera. Maybe the first sentence just needs to be rewritten in past tense—Ephemera was transitory written and printed matter not intended to be retained or preserved, but now the internet retains and preserves everything, so it’s essentially a concept that doesn’t exist anymore.
