Theme 1 – Price & Purchase Concerns
- “About $340 for the full set of eBooks.” – jagged‑chisel
- “They're really good quality though (even if they are very expensive).” – disgruntledphd2

Theme 2 – Format & Quality Preferences
- “Do they have wide margins like a printing or tight margins for tablets?” – philips
- “The valuable prose aside, I never liked that code examples were in a pseudo assembly language.” – zerr

Theme 3 – Community Reverence & Nostalgia
- “I am not a believer, but pray that whichever DEITY is watching over Donald Knuth allows him a healthy and long life to reach the achievement of finishing volume 7.” – TheChaplain

These three themes capture the dominant discussions: the high cost of acquiring the PDFs, the specific format and readability concerns, and the affectionate, almost ceremonial respect the community holds for Knuth’s work.
