Collections and Volumes
From Griffith
Collections and volumes allow you to specify the relationship between movies. They assist you in grouping movies on different levels.

What Volumes Are For
A volume groups together movies that are to be handled as one, probably due to physical restraints. Whenever loaning one movie makes another unavailable you should use a volume to group them.
A movie can only be assigned to one volume (but you can of course clone the movie entry and assign the clone to a different volume, if that makes sense in your situation).
Example
Let's pretend we have a DVD with three Charlie Chaplin short films. You may want to create a movie entry for each of the short films to keep their metadata (like rating, actors, etc.) separate. However, when you loan the first short film, the others become unavailable because they are on the same DVD. So you should group them using a volume (e.g. "Charlie Chaplin filmlets: title1 - title2 - title3").
What Collections Are For
A collection can be used to group one or more physical media together (but Griffith only cares about the movie entries assigned to a collection, so it could also be used for purely logical grouping).
A movie can only be assigned to one collection (but you can of course clone the movie entry and assign the clone to a different collection, if that makes sense in your situation).
Loaning Collections
When you loan a movie that is in a collection, Griffith automatically asks if you want to loan the whole collection.
Some observations that you might find useful:
- When loaning a movie that is in a collection and you choose to loan the whole collection, you (of course) only really loan any movies in the collection that are not loaned already.
- When returning a movie that was loaned together with other movies in a collection, all of them are returned at once.
Limitations of Collections and Volumes
As noted above, a movie can only belong to at most one collection and at most one volume at any given time. You can use Tags to work around this.
