Still to find

The 616 Road to Secret Wars isn’t in the library yet. 1 issues to track down before that leg is readable. Computed against every comic on the Books volume, so anything already on disk is excluded.

Already on the shelf

Secret Wars #2–9 and most of Time Runs Out (Avengers #35, #40–44, New Avengers #24) are already in the library — so the gap is smaller than it looks. Secret Wars #1 is the one conspicuous miss.
