CREES, then in the Ashley Building, was a rich academic environment. Everyone shared their specialist knowledge and all loved the wide-ranging conversations in the Common Room. There were always interesting visitors. Jenny Brine would lead us through the rich resources of the Baykov Library. Probably the most important thing I learned from the CREES folks, and especially Bob Davies, was the importance of the footnote. It documented conclusions and sometimes it changed them. They had to be explained, even if they messed up your theories. It’s not as if he told me this, but it was in the air.
