[2][3] In December 2013 the ICHEG received a donation of several SSI video games, for instance Computer Bismarck, notable for including the source code for preservation.

ICHEG is additionally supported by a research library of more than 130,000 volumes, including vintage comics and children's books and the largest collection of toy catalogs in the United States.

The collections include: The ICHEG takes a five-pronged approach to video game preservation: Original Software and Hardware, Marketing Materials and Publications, Production Records, Play Capture, and finally the Source code.

Through grants from the Institute of Museum and Library Services, ICHEG is in the process of making all of its collections catalog available online.

In a weekly blog, the CHEGheads—three experts from the International Center for the History of Electronic Games and their special guests—spotlight key and unusual artifacts from the ICHEG collections.
