What about the ISEC? (here). Each year ISEC members select a topic of importance to the development of space elevators and their operation.

The topic is researched in depth and a report is published most years containing their findings:
2023: The Climber-Tether Interface of the Space Elevator
2021: Space Elevators, the Green Road to Space
2020 #2: Space Elevators are the Transportation Story of the 21st Century
2020 #1: Today’s Space Elevator Assured Survivability Approach for Space Debris
2019: Today’s Space Elevator, maturing into the Galactic Harbour
2018: Design Considerations for the Multi-stage Space Elevator
2017: Design Considerations for a Software Space Elevator Simulator
2017: Space Elevators: A History
2016: Design Considerations for the Space Elevator Apex Anchor and GEO Node
2015: Design Considerations of a Space Elevator Earth Port
2014: Space Elevator Architecture and Roadmaps
2013: Design Considerations for Space Elevator Climbers
