Recently, this question arrived in the BOTD inbox:

“Interested in looking through the Index listings for the 1930s, 1940s and 1950s. Can this be found online?”

The answer is YES. All of J.M. de Bujanda et al.’s Index des Livres Interdits may be found online via Google Books here.

I also went ahead and broke down my response by year to more specifically address the above question:

1930	1940	1950
1931	1941	1951
1932	1942	1952
1933	1943	1953
1934	1944	1954
1935	1945	1955
1936	1946	1956
1937	1947	1957
1938	1948	1958
1939	1949	1959

Of course, you can also insert any other years into the “Search in this book” bar. As in the canned searches above, just make sure to disregard from the results any entries that do not refer to condemnations but are rather an author’s birth or death year, for example.
