The Alliance of Independent Authors (ALLi) is aiming to open new groups internationally this year, following the launch of a branch in Switzerland this week.
ALLi founder Orna Ross said the new groups would help self-published writers to share ideas and solve common problems.
She said: "Lots of writers work globally online, but having local support can be helpful too. We have established groups in London, Dublin, the US and now Zurich, but want to add more." ALLi will be at this year's London Book Fair during its first anniversary.
