This subdomain is part of the excudo website
In here you'll find Tools (soon), Scripts & some of the papers i've written (and will write in the future) about topics that form a bridge between psychologyand the internet.
The reason i created this subdomain is to have an outlet for my creative moments and to be able to share them with my fellow nerds.
Enjoy the contents, but read the disclaimer first.

Name: isbn check
Checks whether a string is a valid ISBN (International Standard Book Number) number
