Festschrift
In academia, a Festschrift is a book honouring a respected academic. The term, borrowed from German, could be translated as celebration publication.
A Festschrift contains original contributions by the so-honoured academic's close colleagues, often including their former doctoral students. It is typically published on the occasion of an anniversary. A Festschrift can be anything from a slim volume to a work in several volumes. It often includes important contributions to scholarship or science.
There is no fixed anniversary for a festschrift but they are frequently published on an academic's sixtieth birthday in Germany.

However, Festschriften are often titled something like Essays in honour of... or Essays presented to...
