At present, historic terms like “form follows function” need to be interrogated a little more critically if they are to be applied to current conditions, How will you ascertain the “subjective … personal take” of architects ?

The proposed methodology is unclear.
How will you ascertain the “subjective … personal take” of architects ? What does that even mean ?
I am not sure why you have cited historic architects, but no recent architects or relevant case studies
Also, apart from Hans Sharon, none of the architects you list have designed libraries.

Over the last 20 years there have been some important and interesting debates about the meaning, future and function of libraries in light of digital technology, access to knowledge, archiving, and the role of the library as a public/civic/political space. New public library programmes are more than just functional. At all scales, varying in scope from nation to town, the public library is being framed globally as an emblem of hope and a symbol of cultural establishment. It is often the symbolic- and Instagram-friendly – value of enabling the physical browsing of books that is celebrated today.
