A fact from this article was featured on Wikipedia's Main Page in the On this day section on October 31, 2008.

I am currently in the special collections reading room at the library, working closely with the curators. Can I ask on their behalf that medieval manuscripts be cited by the three-letter form that is preferred by the library rather than the sundry longer forms found in older literature. If in doubt, check their website http://www.library.leiden.edu/special-collections/manuscripts/. So for example:

• BPL 3 - not, for example, MS lat 3 or Bib pub L3
• VLQ 3 - not, for example, Vossianus Q 3 or Voss lat 3q
• VUL 3 - not, for example, Ms. Vulc. Lat. 3
• SCA 3 - not, for example, Scaliger Lat 3
• LTK 3 - not, for example, Ltk. 3 or MS letterkunde 3

It is difficult, I know, because there is so much inconsistency in the literature, but getting it right is a courtesy to the library, and helps us all in the long run. --Doric Loon (talk) 12:47, 10 March 2012 (UTC)[reply]

The official name of the library is since a few years: Leiden University Libraries. See for instance: https://www.library.universiteitleiden.nl/

Dutch entries as of 2025 are listed here: https://www.unesco.nl/nl/nederlands-memory-world-register . The claim in the first paragraph which i moved here:

Furthermore, Leiden University Libraries is the only heritage organization in The Netherlands with five registrations of documents in UNESCO's international Memory of the World Register.

needs some other reference. Thanks, Hansmuller UBL (talk) 12:26, 6 March 2025 (UTC)[reply]

OK. "Memory of the World International Register". unesco.org. UNESCO. Retrieved 13 March 2025. Search for Netherlands in the menu, then in total 20 entries are found as of 13 March 2025. 5 of them are curated at Leiden University Libraries, although La Caligo (Leiden) is only explicitly mentioned in the UNESCO Nomination form on the linked webpage.

The article contained an interesting claim:

It is regarded as a significant place in the development of European culture: it is a part of a small number of cultural centres that gave direction to the development and spread of knowledge during the Enlightenment. This was due particularly to the simultaneous presence of a unique collection of exceptional sources and scholars.^[1]

The source does not seem to elaborate on this explicitly. Can this claim be verified using research references? Thank you, Hansmuller UBL (talk) 14:31, 19 March 2025 (UTC) Hansmuller UBL (talk) 14:31, 19 March 2025 (UTC)[reply]

By the way, this claim does not touch on the library itself directly, as it is about Leiden University as a whole, which makes it of lesser relevance here. But still. Thank you, Hansmuller UBL (talk) 15:51, 20 March 2025 (UTC)[reply]

The section History contained a spectacular claim:

According to Nicholas A. Basbanes, Leiden University Libraries represent "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."^[1]

Can these claims be substantiated? Thank you, Hansmuller UBL (talk) 14:39, 19 March 2025 (UTC) Hansmuller UBL (talk) 14:39, 19 March 2025 (UTC)[reply]
