The AIU Digital Library allows now to display two images facing each other so that you can compare different documents, books or photographs.
Thus, it will become much easier to study various texts on the same subject at the same time, to compare the same building at two different periods, to identify certain people (via their photographs or their handwriting) or to carry out many other connections. It’s up to you to seize this tool and use it as you wish!
