I don't remember anything like that on DLM and I saw every ep. I don't think there is a DLM wiki about this.
I think there was reference to archives in the Charmed ep "ex libris" or something like that.
There's a cool music video that takes place in a library: Tears for Fears "Head over Heels"

There is also a cool ep of Avatar that takes place in a library/archive/storage facility
you're going to laugh, but that actually sounds like an episode of Ghost Whisperer that i happened to see once.
Ooh, new cliched tv scene for the collection.
I was actually thinking it happened on an episode of the X-files!
And I was thinking it had happened on an ep of Angel!
Well, there is the Files and Records girl, but I don't know if that counts as an archive.
My friend found the episode she was thinking of. It was Dead Like Me:

oh that episode? interesting.
"She" showed up on my Tivo today.
I watch that ep every single time Tivo captures it. The dancing!
So, we're up to S6, and we're watching "All the Way" (the Halloween episode), which I hadn't really re-watched, and Xander's Halloween costume? Pirate.
Complete with EYE PATCH. Holy foreshadowing, Batman!
I said, "Yikes!" and had a hard time not spilling the beans to The Boy about the S7 eye-gouge.
