Since you did not specify a citation style (APA, MLA, Chicago, Harvard, etc.), I will provide the most common academic formats. If the source is a standard academic article but a blog or personal website (as the name suggests), the correct citation should reflect that. Assumed structure for “bibliotecasecreta.nl” For all examples, I will use a placeholder page title. You must replace [Page Title] with the actual title of the specific page you are citing.
Biblioteca Secreta (n.d.) states that… bibliotecasecreta nl
or if the author is “Biblioteca Secreta”: (Biblioteca Secreta) Since you did not specify a citation style
