I'm sorry to hear that Charles N. Brown, publisher of Locus for the past forty years, has died.
For some memories of him, see Making Light, and Graham Sleight's personal eulogy. I'm sure there will be many more such posts in the hours and days to come. (And I'm sure there have been many others already; I don't intend this as a comprehensive list, just a couple of samples.)
I didn't know him well, but my condolences to those who did.
He and his staff have done an impressive job of documenting the sf publishing world for decades; I'm glad to hear that Locus will continue, with Liza Groen Trombi stepping into the editor-in-chief role.
