While the majority of published material in the collection was removed and catalogued during processing in 2011 and 2025, a small number of published works were kept in the collection, mostly serials, newspapers, and broadsides. These works are largely publications that contain Peacock's articles and poetry, although there is also a small collection of broadsides by other authors.
