A collapsible ring binder (40) includes a plurality of selectively openable and closable rings (10) that releasably retain hole-punched documents within the binder. The rings (10) may be collapsed and/or detached from the binder (40) to flatten the binder for transportation and/or storage. The rings are easily moved from their collapsed and/or detached configuration to their upright and usable configuration so that an end user can easily ready the collapsed binder for use.
