Welcome to my user page. My work on Wikisource concentrates mainly around writing scripts for automated tasks, but I also contribute and proofread texts when my time allows it, mostly in the areas of science and mathematics.

I'm an admin since 26 December 2006, together with my bot, TalBot. You can contact me via my talk page. If you need general admin help, you can also leave a message on the admin notice board.

If you have a request for an automated task, please visit the bot requests page.

Texts I'd like to contribute but can't

An Axiom in Symbolic Logic by C. E. Van Horn

In the light of A Reduction in the number of the Primitive Propositions of Logic, this text would be a nice addition to Wikisource. It was published in Proceedings of the Cambridge Philosophical Society (Volume 19) in 1920, i. e. before 1923 and thus should be uploadable to Wikisource. But not by me because I live in the European Union and have to pay attention to the local laws as well. According to these laws, I cannot upload works by C. E. Van Horn before he has been deceased for 70 years. Unfortunately, Mr Van Horn is somewhat elusive in matters pertaining to his death date. The facts:

• His work An Axiom in Symbolic Logic was written at Baptist College, Rangoon, Burma (now probably Yangon University, Yangon, Myanmar), source: photocopy.
• Edith Van Horn was born to Clarence Eugene and Alice Van Horn (née Owells), Baptist educational missionaries in Rangoon, Burma [2]. It is extremely likely that her father is the person we are looking for, so his full name is Clarence Eugene. The source says nothing about the fate of her father. It does, however, mention that the family settled in Nashville, TN.
• The paper The Simson Quartic of a Triangle, published in Amer. Math. Monthly, volume 45 was written by C. E. Van Horn at Fisk University in 1938. This university is located in Nashville, so this should be the C. E. Van Horn we are looking for.
• The box listing [3] refers to "Correspondence and Contracts" of C. E. Van Horn from 1929 until 1944. So if Van Horn was alive by 1944, I cannot upload works by him until (at least) 2015.
• For reference, there is also an entry in the Math Genealogy Project: [4].
