Sorted, categorized collection of links to over 170 articles.
Notes
The total Encyclopaedia Iranica currently consists of around 9,000 articles, and is not yet completed. Other articles, more directly related to the Bahá'í Faith, can be found elsewhere at Bahá'í Library Online.
Note that the column "Description and comments" is AI assisted (edited output of questions to ChatGPT 3.5 like "summarize text in maximum 25 words"). Without that it would have been much more time consuming to create.
Tip: To read long articles on the Encyclopedia Iranica on a (mobile) screen can be inconvenient for some. It may be helpful to copy and paste content that interests you into a Word file and then and send it to your e-reader or e-reader app (if needed after converting it to EPUB format (with software like Calibre).
