June is...
Materials about weddings always disappeared from my libraries. However, since weddings and June and religious materials are often inextricably bound together, one of the books we keep on our reference shelf is Monger's Marriage Customs of the World: From Henna to Honeymoons. (ABC-CLIO, 2004)

The subtitle is misleading as the book does go from a-z. Almost any question you or your patrons may have about wedding customs and culture is found here accompanied with references to other resources. This book is recent enough to include mention of current developments in marriage. I plan to use it to locate other books-- even if they also disappear.
