Don Seiffert of the Boston Business Journal reports that Boston Globe editorial-page editor Ellen Clegg has announced her retirement, and he notes that sports editor Joe Sullivan recently said he would retire as well.

I suspect the sports section will be just fine. Clegg’s shoes, on the other hand, may prove to be difficult to fill. A longtime Globe employee, Clegg followed Peter Canellos, an exceptionally thoughtful editor who took a top job at Politico after leaving the Globe several years ago. Clegg proved to be an innovator both online and in print. More important, she has a close working relationship with owners John and Linda Henry, which has really mattered given the Henrys’ ongoing interest in the editorial pages. You’ll find a synopsis of those innovations in an interview I did with Clegg for the Nieman Journalism Lab earlier this year.

And now for some personal news. For the past several months Clegg and I have been talking about working together on a project, probably a textbook about opinion journalism. I’ve known for a while that she was retiring — the project is not something I could take on if she’d stayed at the Globe given the conflict of interest with my work at “Beat the Press” and WGBH News. So I’m glad Clegg’s departure is finally out in the open.

Although we’ve sketched out a few ideas, we are a long way from producing anything. She’s not leaving the Globe until mid-August. I just wanted to let you know that Ellen and I will be working together before you heard it from anyone else.
