The Library of Identification Resources was featured in De Levende Natuur, a Dutch nature magazine (published since 1896) in the rubric "New keys"!

"Maria and Peter are students and meet up for a late dinner. Peter asks Maria whether Tom is at the party that they intend to go to after dinner. Maria answers that Tom is at the party. But Maria is just guessing, she hasn't heard from Tom whether he would come or not. When they arrive at the party, it turns out that Tom is indeed at the party. Was Maria's answer true or false?"
(please spread for visibility, I would like this to be as wide as possible)
yeah, sorry, no updates to the ISAAC Browser Extension. It just works.
Do you have to add NWO grant research output to the ISAAC database, and tired of entering all information by hand?
Then install this browser extension: https://chromewebstore.google.com/detail/isaac-chrome-extension/kiljfbiapahlahhilgcgfkfjnkgggode
And plz tell your colleagues!
A "fun" bibliographical data modelling problem that I am running into: Odo Reuter published his "Hemiptera Gymnocerata Europae" in five volumes from 1878 to 1896. Vol. 3 includes supplements for vols. 1-3 and vol. 4 and 5 include their own supplement (it seems). None of the volumes have their own title.
The whole thing was then reprinted in parts in Acta Soc. scient. Fenn.: vols. 1-3 with their supplements in vol. 13 (1884), and the rest in vol. 23 (1897).
Very niche taxonomy pet peeve: authors who don't distinguish between the author citation associated with a name, and citations of publications where a name is used.
How are readers meant to tell which of these names are misapplied and which are true synonyms?
After just having responded to the third #curl security report for the evening I noticed a post that cheered me up...
Have a good Friday everyone!
