• Sorted by the total number of books (or volumes) in which the term is found, with the highest count first.
• Uses Google's 2012 "English (All)" Ngram corpus. This includes scanned English-language fiction and non-fiction books.
• Homo sapiens (#1) was found in 87,380 volumes. Pseudomonas fluorescens (#100) in 6,562.
• 30,019,350,634 lines of Google's 2gram data were parsed to create the list. 0.009% of lines were relevant (i.e. contained a species name). The script completed after running continuously for 6.5 days and downloaded around 120 GB of compressed data.
• If anyone's interested in further processing the generated data or in some variant of it, let me know what you'd like to do so I can send you the relevant file(s) or see what I can do.
• 51 of the 100 listed scientific names are red links on en.wikt (at time of this posting). Twelve of the top 1000 are red links on English Wikipedia, but this does not include any of the top 100 (this list).
• I've generated more specific lists which show only plants or vertebrates. When I have time, I may attempt to generate lists for other categories such as invertebrates, or a list just of genera, or perhaps an auto-updating list only those with missing entries or etymologies, or restricting the search only to fiction.

Inclusion criteria for species found in books:

• Had to be found already capitalized with the modern convention used for binomial names (i.e. the only capital being the first letter of the genera)
• Had to be also be found in the Catalogue of Life. Of CoL's approx 2,485,495 binomial species and synonyms, only 52,669 were found in books.
• Had to appear in a minimum of 40 books (or volumes). This appears to be the minimum to be included in Google's 2gram data.
• Trinomial names (e.g. subspecies) would have appeared as binomial to the search, and counted as such.
• Only books published after 1950 were included in the tally. This is partly to keep it current and partly to keep it fair: some binomials were capitalized differently before this date, so would have been left out in the final tally. (See the note on "botanical works published before the 1950s"). However, volume counts in these notes include the totals of all years available.
