A. ROSS ECKLER was the first to answer all the unsolved posers in the November issue. He wrote:
Knuth's puzzles are based on mixup, premix, and simplex; the two-letter puzzles by Harold Jacobs are based on names of states and territories, Scrabble two-letter words, two-letter elements, and ANSI two-letter standard codes for countries. I solved the Nongram Christmas Card (HAPPY XMAS) without using the alphanumeric substitution: noting that E seemed to mark the space between letters, I noted that the letters were of the form SSNNS SSSN where 5 stands for right-left symmetry; also, the second letter of the first work is the same as the third letter of the second word.
I was especially intrigued by Ronnie Kon's article which lays out the structure of various types of hypercubes. There has been little study of this in Word Ways since Darryl Francis created various hypercubes (up to 5 dimensions) in the 1970s.
Also, I recently noted a panalphabetic index of only 397 items in Deep Ancestry Inside the Genographic Project (National Geographic Society, 2007) by Spenser Wells. This is nearly equal to the 394-item panalphabetic list of language names in Roget's International Thesaurus (1977), mentioned by El Wolpow in the Aug 1984 Word Ways.
And did you know that the predecessor of your CLINTON/BOBDOLE crossword appeared in the May 1981 Word Ways (for CARTER/REAGAN)? (The Editor: Yes, when it did not run in the 1980 NY Times, I gave a version to Word Ways)
The answers to DONALD KNUTH's "Latin Square Word Puzzles" are:
Professor Knuth notes also that the IPP was number 29 thereby accounting for the XXIX in (b) and (c). The answers are unique.
HAROLD JACOBS also solved Knuth's puzzle and submits a new poser:

What exactly is going on here?
AL BACKIEL adds to Jacobs' table 3:

CHRIS COLE notes that Rex Gooch's 6+ million word and name list contains the following 15 letter near-palindrome:
