According to Nicholas A. Basbanes, Leiden University Library represents ""an essential benchmark [...] not only for the teeming collection of extraordinary materials it has scrupulously gathered and maintained over a sustained period of time, but most of all for being the world's first scholarly library in a truly modern sense. The litany of 'firsts' recorded at Leiden is dazzling - the first printed catalogue to be prepared by an institution of its holdings, the first attempt to identify and maintain what today are known as 'special collections,' the first systematic attempt to develop a corps of influential friends, patrons, and benefactors throughout the world, the first 'universal' library, the list goes on and on - and underpinning it all is a humanistic approach to education and discovery that has figured prominently throughout its history, along with an unbending belief in the limitless potential of human inquiry.""
