Lille Before and During the War is one of the Michelin Guides. The Michelin Guides are a series of guide books published by the French tire company Michelin since 1904. Michelin also publishes the Green Guides, a series of general guides to cities, regions, and countries. During World War I, publication of the guide was discontinued. After the war, modified editions of the guide resumed to be given away until 1920. They made various modifications, like listing restaurants by specific categories, adding hotel listings, and withdrawing advertisements from the guide. After acknowledging the increasing popularity of the restaurant section of the handbook, the brothers recruited a team of inspectors to visit and review restaurants, who were always unknown.
