Manga Editions guide
Edition Data Change Log
Substantive changes to the sourced Manga Editions catalog and calculation method.
September 9, 2026: launch catalog
Published the initial 20 series maps, 55 verified collected-edition contents records and 10 practical guides. Each record links to its publisher or authorized distributor source. Missing ISBNs and unverified bonus material are explicitly labelled.
The calculation separates owned books from candidate editions, preserves gaps, and keeps series numbering isolated. Berserk Deluxe 14’s guidebook is separate from volumes 40–41; Vinland Saga uses original-volume units. Announced One Piece Box Set 5 remains outside the released-edition calculator pending its release check.
