I'm not kind of man which copy all games and programs holding in the hand. But there came time when I wasn't able to keep order in my collection. There was need to create some list and keep it. I didn't know many databases for Spectrum and no one seemed to me good at all. So I wrote my own. It used property of lists that many informations are stored many times to store more records into memory. This informations are stored in library only once.
