When I first spent significant time in London, about fifteen years ago, one of the first words that struck me as unusual was book–used as an all-purpose verb to indicate, well, as the Oxford English Dictionary puts it: “To engage for oneself by payment (a seat or place in a travelling conveyance or in a theatre or other place of entertainment).” The OED cites a first use in Disraeli’s 1826 novel Vivian Grey –“I’ll give orders for them to book an inside place for the poodle”–and then an 1887 theatrical advert: “Seats can be booked one month in advance.”
In London a hundred-plus years later, people were always talking about booking theater, excuse me theatre, tickets, hotel rooms, tables at restaurants. (Granted, this came up a lot because I was in a tourism/study abroad situation.)
The usage was not unheard of in the U.S., but (the significantly less strong) reserve was much more common in reference to eating and sleeping. For theatre, I guess our best word has been get, which isn’t very good. Hence it’s not surprising that book has gotten traction here.
