Congratulations to the winner of the drawing, Amanda Giermann!

The first thing to do is the obvious: decode the message. Correctly decoded, it reads as follows:

USING BARTON (HTTP://LIBRARIES.MIT.EDU/BARTON), REQUEST A PDF SCAN OF THE FOLLOWING ARTICLE, WHICH WE HAVE IN STORAGE:

BATCHELOR, B.G., CLASSIFICATION OF POLE MAPS IN COMPLEX PLANE. JOURNAL OF CYBERNETICS, 1978. 8(3-4): P. 237-251.

KEEP IN MIND THAT THE LIBRARY STORAGE ANNEX IS ONLY OPEN FOR SCANNING MONDAY THROUGH FRIDAY, NINE TO FIVE.

Decoding this block of text, however, is only the first half of the puzzle. The next step is to follow the instructions and go to Barton and request that paper. The Library Storage Annex would receive the request, but instead of scanning the paper, would forward along the second part of the puzzle.

The second part of the puzzle first asks for three words which are clued in from the first part. Those words are SLY CODING ZEBRA, and can be found by looking at the code used in the decryption:

Decoded Letter A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Coded Letter S L Y C O D I N G Z E B R A F H J K M P Q T U V W X

Next, you need to change a letter and descramble each to obtain three shades of blue. This just take a little bit of figuring:

Word Change letter To Letter Descramble Shade of blue
SLY L K SKY SKY
CODING C I IODING INDIGO
ZEBRA B U ZEURA AZURE

Next, we need to fit these letters into the grid as specified, and find four shades of green. The completed grid, with the shades of green highlighted, is below:

And so, removing the shades of green, the words that we can take out of that are BUSY REDEFINING SPECTRA. And again we just need a little figuring to change a letter and descramble each word to get a shade of red:

Word Change letter To Letter Descramble Shade of blue
BUSY S R BURY RUBY
REDEFINING D E REEEFINING FIRE ENGINE
SPECTRA P L SLECTRA SCARLET

Finally, taking the appropriate letters from those words, we get the answer, INFANTRY.
