I spent a lot of time in the last few years working at the place depicted (the Goldfarb Library at Brandeis University).  Later, I worked at the Library of Chapman University, Fairfield.  There's nothing morally repugnant about a library.  You take books that cost money & make them available for free.  It fights the existing socioeconomic order while promoting literacy for all.  Sure, nothing heroic per se, but nothing bad either.

It's hard to say whether there was ever a library run out of a pyramid.  The Egyptian pyramids were built with such precision that the resident culture must have been extremely literate.  They would later prove this with a Great Library in nearby Alexandria, whose burning is arguably the most tragic event in history of those events where the loss of life was not substantial.  The loss of knowledge was monumental.

Books are often blue.  I know, because when I worked at the Goldfarb Library, students would often ask for books by their color alone.  So much for not judging books by their covers.  One might find it difficult to believe that kids selected for a top fifty university education could identify books only by non-verbal elements, but I assure you that the frustrations of looking for "the blue book about China" are serious.  Library editions of books tend to be solid-colored, making their blueness more prevalent than the average illustration-covered book.

This Blue Pyramid Library has a few components.  Luckily for you, an understanding of where to find DT73.K28 D38 1986 or some such volume is not essential to navigating through them.

As yet, there's a book list project going on.  Two parts here:
1.  See my picks for the 25 best books ever.
2.  See everyone's picks for the 25 best books ever.

Soon, there should be more.  For example, I want to revive a list of my so-called "Collected Works".  As yet, the relevant thing is that I've written Loosely Based, a novel, published in 2003... you should read it!  There's also 60 or so short stories & a bucket of poems.  But that has a smaller subscription.

You should also bop over to my favorite books I read in 2001.  Just for kicks.
