the organization may seem a little weird at first pass, think of it as a collection of multiple libraries.
a "module" is a library/collection, within a module you'll see "anthologies" (a collection within the library), and then collections, and then individual items
so for example Dark Horse has a "module" - within it are anthologies like "Aliens" and "Buffy Universe." within the anthology there are collections for the different series within, and then the items are the actual books
