Encyclopedias are published in many places around the world by different publishers. Some well-known examples include:
* Encyclopaedia Britannica: Originally published in Edinburgh, Scotland, it is now published in Chicago, USA.
* Wikipedia: A collaborative, open-source encyclopedia published online globally.
* The World Book Encyclopedia: Published in Chicago, USA.
* Oxford English Dictionary: Published in Oxford, UK.
To be more specific, you need to tell me which encyclopedia you're interested in. For example:
* "Where was the first edition of Encyclopaedia Britannica published?"
* "Where is Wikipedia published?"
* "Where was The World Book Encyclopedia first published?"
Let me know the specific encyclopedia, and I can help you find the answer.
