Dear fellow scientists, here's sth that puzzles me at present: In virtually all research repositories that I know, PDF documents dominate, even though they are a 1990s format targeted at bringing classical paper documents to screen, without being resonsive not linked. Back in the 90ies, though, Tim Berners-Lee proposed another format with hypertext capabilities for scientific exchange. Why do paper-page-style PDF still dominate so much? Do you have ideas? Or do you know about other formats that may exist out there in communities beyond mine (chemistry/physics/materials science)?
