 The distribution of nomenclatural acts in different publication titles follows a "long tail" (leptokurtic) pattern. We have visualised the number of nomenclatural acts per publication titles and their open / closed statuses using a more restricted time scale (2019-2021), to better reflect current working practices (Figure  @fig:fig3). For legibility, we cut the "long tail" at 80% of the dataset.
 When analysing the IPNI data, we find that many journals active in the publication of nomenclatural acts are undiscoverable - the containing bibliographic work is not labelled with a DOI (Figure  @fig:fig3) - or the acts are labelled with a DOI which is now unresolvable ($dois_unresolvable$ in total, in $publications_w_unresolvable_dois$ different publications).

 ## Open access takeup by distribution
 
 Africa, South America and South Asia, some of the botanically most diverse areas, have the greatest proportion of undiscoverable nomenclatural acts (Figure  @fig:fig4 (i)), whereas Europe, North America and Australia have the lowest proportion.  When considering only the discoverable literature using DOIs (Figure  @fig:fig4 (ii)), South America and South Asia have the lowest proportion of open publication of nomenclatural acts, though Africa  has a higher proportion.
