    H.O. 214 was originally published between 1936 and 1946 as each volume
    was computed. It consists of 9 volumes each covering 10� of latitude.
    My set has various publication dates between 1940 and 1970. Thank you
    for the errata sheet. I checked my volumes covering 40� to 59� which
    were published in 1962 and found that the correct values were already
    printed in my set.
