"The maintenance crew was performing routine cleaning of students' quarters after several graduate students recently finished their projects here at the library. It's common to have a lot of turnover this time of year, and we typically reclaim many living quarters.

"As you might imagine, many of the quarters are in deplorable condition and require extensive reclamation. At any rate, in one set of living quarters our staff had to rebuild a wall. While they were clearing the existing rubble, they found two fragments. They recognized the string of numbers as something important and brought the fragments to me.

"We were actually quite lucky, because the maintenance crew knew about our ongoing research. Had these fragments been discovered at any other time, I seriously doubt that the cleaning crew would have bothered to save them. Most likely, they would have been recycled with all the other debris."

Dziga said it will probably be impossible to determine who originally possessed the fragments, and why they were left behind.

"So many students come and go through here. I highly doubt we'll ever know where these fragments came from, and how long they've been here. But I should stress the fact that we don't believe there is any conspiracy or foul play involved. Most likely, these were discovered during someone's travels, and while at the library, the owner tried to decipher them. Why they were hidden, and why they were left behind, is anyone's guess."

The most important aspect, Dziga said, is that the fragments have now been added to her own growing collection. After verifying the fragments' authenticity, Dziga said she decided to immediately make the fragments available to the public.

"There is no reason to keep these secret, particularly in light of all the help we've gotten from citizens across the galaxy. I believe that the more open and honest we are about this research, the more quickly we'll get this puzzle figured out. The support and diligence of all these amateur cryptographers has, quite honestly, made my job much easier. Some of my colleagues were of the opinion that we should withhold these fragments from the public, but I decided that I simply could not do so. The outstanding efforts of the dedicated public have greatly advanced our own research, and I could not in good faith withhold this information."
