Overview of holdings from a sample of thirteen well-known NHCs that together house approximately 392 million individual specimens. Holdings are colored by taxonomic group. The exact proportion of specimens accounted for by each group is listed in parenthesis; the percentage of each group that is digitally databased and online-accessible (“online”) is also listed. For fish, insects and other invertebrates, collections are typically made as lots, where individual lots may contain tens to thousands of specimens, thus, estimates for the number of specimens in these collections are approximate. The 13 NHCs summarized here are listed in the caption for Figure 3.
