To do this you have to add an event handler to the event copy .

Within this handler you have to get the text already selected and then add the new part.

Example:

function addLink(e) {
    e.preventDefault();
    var copyright = ' - Ler mais aqui: www.google.com';
    var novoTexto = copytext = window.getSelection() + copyright;
    (window.clipboardData ? window : event).clipboardData.setData('Text', copytext);
}

window.addEventListener('copy', addLink);

In some browsers clipboardData is a property of event , in IE it is a property of window , hence the window.clipboardData ? window : event
