For those researchers who would be interested in the Kingdom Ministries before those that appear on the WT Library CD-ROM (which starts at the year 1970):
Here are two more years (US edition), which can be downloaded at the following filesharing site:
1968 Kingdom Ministry (27 MB)

1967 Kingdom Ministry (24 MB)

Finally, here is a reduced size PDF for the 1966 KM, which was posted earlier.

These are all bookmarked and searchable. The 1967 and 1968 KMs reflect more of the excitement for the end of 6,000 years of man's existence in the year 1975. (See the March 1968 KM, p. 4, for example.)
Best wishes for the New Year!
