GCstar is a personal collections manager. Detailed information on each item can be automatically retrieved from the internet and you can store additional data, such as the location or who you've lent it to. You may also search and filter your collection by many criteria.

Current version manages collections of Movies, Video games, Books, Music, Numismatic and Wines. It lets also users define their own types of collections.

GCstar is the successor of GCfilms and provides for movies the same features as GCfilms did.
