var isbn = document.querySelector('[itemprop="isbn"]');
var m = location.pathname.match(/\/book\/show\/(\d+)/);
var bits = [];
if (m) { bits.push('id ' + m[1]); }
if (isbn && isbn.textContent.trim()) { bits.push('ISBN ' + isbn.textContent.trim()); }
var title = document.querySelector('.bookTitle, h1[data-testid="bookTitle"]');
if (title && bits.length) {
var tag = document.createElement('small');
tag.style.cssText = 'display:block;color:#888;font-weight:400;font-size:0.8rem';
