The documents seem to be multiplying; this is only because they have been separated from each other, from their bundle, and now cover a goodly portion of the floor, the table, the windowsills. Some documents are instead collections of color printouts of digital photos of some of the books and papers and wallplates found in the bases and spaceships.
The script is clearly human; it is, as has been said, somewhat reminiscent of cuneiform, but at the same time it is not cuneiform. There are few breaks between characters, or groups of characters, whatever they are, and the text is dense wherever it appears.
Tentative translations are found in handwritten notes in the margins: “this is the ship [unknown]”; “go quick[xxxxx] [unknown] [unknown] sky”; and the like. Questions make up most of the notes: “related to Assyrian?” “Hebrew cognate?” “Egyptian?” Two hands wrote these notes, and there is little agreement to be found in their understanding (if it can be called that) of the text. Statistical analyses are cited; comparisons with known languages and writings systems are made; confusion and frustration predominate.
