Here is the code to the Theological Journals Search widget that anyone is welcome to use to embed the search box into their own guide or web page:

<script>
(function() {
var cx = '018443097211386924752:luwi5uy2qbe';
var gcse = document. CreateElement('script');
gcse.type = 'text/javascript';
gcse. Async = true;
gcse.src = 'https://cse.google.com/cse.js?cx=' + cx;
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(gcse, s);
})();
</script>
