The Electron User Group is responsible for making almost all of the companion discs on the whole of the site available. However, for ease of reference, individual companion discs are located under their original publisher, not under an EUG catalogue.

There were two discs however, which were produced solely by EUG readers - ANIMEWORLD by Dave E and THE JOSEPH LAVERY COLLECTION by Joseph Lavery. These are simple slideshows of artwork.

The disc-based issues of the EUG magazine are located in a separate library.
