The Natty Archives (as we like to say) has also added the ability to search for its GIFs and share them directly on Twitter: click the GIF button when composing a tweet and search "ArchivesGIF." A handy option for when you absolutely must share your love of retro science nostalgia. Take your love of the graphics interchange format to another level at the agency's "Advanced GIF-Making Techniques" webinar class coming up next week on Wednesday, September 28, 2016, from 3 pm-4 pm ET, hosted by the Digital Public Library of America. The classes promises to show you how to make your own GIFs from archive images.
