The following booklets do also have my interest:
1942 Jehovah's Witnesses - Who Are They - What Is Their Work? (32 pages)
1953 Jehovah's Witnesses of Modern Times (32 pages)
1966 Jehovah's Witnesses (32 pages)
1977 Jehovah's Witnesses and the question of Blood (32 pages)
If any could provide any of these as pdf files it would be much appreciated...
