In the United States, nationwide food rationing was instituted in the spring of 1942, and each member of the family was issued ration books by the Office of Price Administration (OPA). These books contained stamps and gave precise details of the amounts of certain types of food that you were allowed. The OPA was in charge of rationing consumer goods such as sugar, coffee, shoes, household appliances, and other goods during World War II.
There were four different series of ration books; each included a different amount of information about the person it was issued to.
In addition to the books collected by Genealogy Today, anyone can contribute items to the registry, either by sending images, photocopies or the original documents. And images already posted online can be registered for inclusion into this new index.
