We strongly believe bringing knowledge to places and things that matter to others is a great way to help others understand our beautiful and complex world. To accomplish this, we invite you to create and distribute Semapedia-Tags which are in fact cellphone-readable physical hyperlinks to the free online encyclopedia Wikipedia (or any of Wikipedias' sisterprojects such as Wikibooks, Wikinews , and Wikinews ). You can create such Tags easily yourself by choosing and pasting a Wikipedia URL into our creation-form . Pressing the button will generate a custom PDF file to download and be printed.
