Quote from the reference needed 

The following sentence has two supporting references:

Each rejected the tag, preferring to identify themselves by the location of their head office, Kevin Street and Gardiner Place respectively. The name of the ('official') party remained Sinn Féin until changed to Sinn Féin the Workers Party in 1977. 

One of them is this book here:

 

which provides page 59 the page cited. A quick review illustrates that the reference does not support the text, therefore I suggest its removal or the text be changed to reflect the source cited. However, there is still the first reference, which may support the text? I would therefore request an exact quote from this book to support the text. From the many books cited on the Sinn Féin article on this subject, none support the text "preferring to identify themselves by the location of their head office" and that is why a quote is necessary.
