At present, I know of as many as four websites that carry one (or, in the case of Bridgeclues, four) new columns/articles on bridge every day: Bridgeclues, Frank Stewart's column, Andrew Robson's column, and Phillip Alder's column (more of an archive). Andrew Robson and Phillip Alder do not write on Sundays.
It turns out you can now download some past columns and summaries (extracts? abridgments?) of four of Marty Bergen's books for easy offline browsing.
- Andrew Robson: January 2007 (incomplete), February 2007, March 2007, April 2007, May 2007.
- Phillip Alder: 2006 Columns, 2007 Columns.
- Frank Stewart, Daily Bridge Club: 1 Sep 2006 5 Dec 2006.
- Marty Bergen: Points Schmoints, Declarer Play The Bergen Way, More Declarer Play The Bergen Way, and Marty Sez.
