The Agentic
Systems Library.

Series ID. 20M5AX5M9QJ was supplied directly by Cowork from a real, signed-in KDP session on Danny's account this afternoon (2026-09-28), reading kdp.amazon.com/en_US/series/20M5AX5M9QJ directly -- not from a summary. This build did not sign into KDP itself and does not independently re-verify the ID; it is shown here exactly as supplied and labelled as such.

The name "The Agentic Systems Library" is used two ways on this site today, and they are not quite the same thing. The whole /books/ page's own page title and breadcrumb already say "Books — The Agentic Systems Library" as a branding umbrella for the entire books section (including the unrelated Rafiki & the… picture-book series). This page, by contrast, is specifically the real Amazon KDP series 20M5AX5M9QJ -- the 10 titles below and only those 10. Both usages are real and both are left as they are; this note exists so the overlap isn't silently glossed over.

Edition mapping: reconciled 2026-09-28. Cowork's first read of the live KDP series page found 18 total rows for these 10 titles -- 8 titles with two live entries each (an original May 2026 edition alongside a revised/re-issued September 2026 edition) and, it first appeared, 2 titles (The Harmonic Theory of Agentic Systems, What's So Artificial About AI?) with one entry each. Cowork went back into a real, signed-in KDP session and checked KDP's own format-level detail view directly: those two titles do have real, live Second Editions on Amazon (amazon.com/dp/B0HKH7GQW3 and amazon.com/dp/B0HKH5M2P5) -- they were simply never added to this series' membership on Amazon, which is why the series page's own row count missed them. This site's own existing books page "Looking for the earlier edition?" links for these two titles -- B0H1ZZMD8T (Harmonic Theory) and B0GX6DDVZQ (What's So Artificial) -- are confirmed correct as those titles' real original May-2026 Kindle editions. The site's own data was right all along; no ASIN here was guessed, moved or invented, and none needed correcting. A separate, real gap this surfaced: three titles that do have two live editions properly grouped in the KDP series -- The Agentic Galaxy, The Agent Architect's Field Manual, Your AI Sidekick -- carry no "earlier edition" link anywhere on the site today. That gap is noted honestly here rather than filled with a guessed ASIN. (Also for the record: the two confirmed Second Editions above, B0HKH7GQW3 and B0HKH5M2P5, still aren't grouped into this KDP series listing -- Danny's own cleanup step if he wants the series membership tidy, not a site defect.) Each individual book page below shows exactly what the site's own existing data already resolves (its Second Edition formats, plus a real earlier-edition link where one already exists there).
