Some of the replies at this assume "Borges" as the cause, the response to "Why".

It can also read as a simple association, as in "this article brings one word to my mind: Borges". In Borges, libraries are a recurrent theme, as there are labyrinths, and Argentinian folklore, timeless, godly structures, etc.

Borges himself basically grew in a library.
