At Salon, Laura Miller writes about...invisible libraries.
The original Invisible Library disappeared from the Web in the mid-2000s (though you can still find snapshots of it in the Internet Archive Wayback Machine), and since then other pseudobibliophiles have opened their own "branches," although these too have a tendency to end up abandoned. The novelists Ed Park and Levi Stahl created a catalog of imaginary titles that inspired an interactive exhibition at a London art gallery, but they have only occasionally updated it since 2008. Loss of interest is, perhaps, inevitable, since when you maintain such a list, tiresome people are constantly proclaiming their disappointed astonishment that their particular obscure favorite isn't listed.
Actually, Levi and I still update our Invisible Library—our "site" is so primitive (i.e., it's a blogspot blog) that we need to keep those 2008 timestamps intact in order to preserve alphabetical order. In other words, we need to get a real site. (No comment about the "tiresome people" statement.)
If you thought we were lying low, you might have missed this one from a few months ago:
