I recently stumbled over the [large collection of mathematical constants](http://www.bitman.name/math/table/181) of Mauro Fiorentini; it is in Italian and appears to be something in the vein of the famous [OEIS](https://oeis.org/?language=english), however maintained by a single person in isolation. 


**Question:**  

what is known about the author of, and the motivation for, that collection of constants and, is something similar available from other sources (the link leads to the first of several hundred tables of constants)?



Collection of Mathematical Constants
Steven Finch used to have a [site full of essays about his favourite constants](https://web.archive.org/web/20020603145930/http://algo.inria.fr:80/bsolve/constant/constant.html) including a [table](https://web.archive.org/web/20020618172325/http://algo.inria.fr:80/bsolve/constant/table.html), though the contents page is actually more interesting


He then turned this into a book *Mathematical Constants* (Encyclopedia of Mathematics and its Applications 94, CUP, 2003), formalising the essays with an expanded table on pages 543-566. The website then shrank before disappearing
