Although there has been no systematic initiative to develop a slide library, each collection department holds some slides that have accumulated over time, mostly reproducing images from our collections. We also have some slides of local gardens from the first half of the 20th century, and some slides are included in various botanists’ papers deposited here. Typically when someone calls to request an image for publication or other use, we arrange with our graphics manager to produce a print, slide, transparency, negative or digital image as needed.
