 In the second half of the 20th century, the practice became used internationally.Since no English term for such a book to mark a special occasion had been in use, the German word "Festschrift" has been incorporated into the English language and is frequently used without the italics that designate a foreign term, although the capitalization of the first letter is usually retained from German.Its plural may be either the original "Festschriften" or anglicized as "Festschrifts".
