How to edit a collective volume of papers from a conference

A collective volume is often a written record of a single conference or symposium, or a record of the “acta” or proceedings of a series of meetings of an organization, often annual, stretching over a number of years; or, finally, a festschrift offered as an acknowledgement of an individual’s professional impact over a significant period of his life. Festschriften are often occasioned by 65th or 70th birthdays, retirement, or other excuses.
