The Colloquia Collection provides information about and access to the Library's audio and video collections of selected current and past colloquia, seminars, and other events. Some of the items may be streamed directly from the online collection. Presentations given prior to 1995 will be audio only.

For information about each of the subcollections and links to the websites of the current Goddard colloquia and seminars, check out the Complete Series List.

Please Note: The Colloquia Collection uses Microsoft Silverlight as its media player. If it is not already installed on your computer, you can find installation instructions for both Windows and OSX at the Silverlight download site.

Since the Silverlight plug-in is a legacy format newer versions of browsers, such as Chrome and Microsoft Edge, may no longer support it, the Library is in the process of addressing this issue. We appreciate your patience and request that you contact us to report any problems.
