Shockwaves of arrest felt across the Atlantic
As news of the politician's release spread, it was prominently placed on the front page of the International New York Times. It also appeared on bulletins on the TV channel CNN.
It was a high-profile story in a country where Mr Adams is a familiar face as he has frequently attended Sinn Fein fundraisers at Irish clubs along the east coast.
The US wire agency Reuters reported that Irish-Americans in the bars of south Boston reacted with shock to the arrest of Mr Adams.
Some worried it would result in trouble once again erupting in the North, while others expressed anger that the US government had cleared the path for the release of the documents held by Boston College researchers, which were believed to be pivotal to his arrest.
Boston College declined to comment, other than to say that it had complied with court orders.
In the UK, the 'Sunday Telegraph' reported that Irish republicans were attempting to compare Mr Adams' plight to that of Nelson Mandela as it covered the unveiling of a 20ft mural of Mr Adams.
Further afield, his arrest, and later his release without charge, delivered eye-catching headlines in Irish emigrant haunts such as Australia, and were also reported by the Middle East's largest news network Al Jazeera.
