The Cuneiform Dictionary is a powerful tool, you will be able to search any sign already present in the dictionary with just few, quick clicks of your mouse. You won't need anymore to scan page-by-page those outdated lexicon's or manual's for locating signs of different historical period than standard Akkadian one. As you know, lexicons are sorted for the Neo-Assyrian version of the signs. So, if you search a sign of a different historical period, you are forced to scan the list of equivalent signs page by page. For not even talking about what happens if you need to guess what a broken sign could be.
