A bibliography is an index, not an endorsement The eight collections classify 626 entries as primary or direct institutional evidence, 133 as secondary or specialist, and 5 as academic. In the VALORANT collection, 135 of 141 records are Riot-published; Riftbound contains 33 first-party records; League esports contains 82; TFT contains 95; Arcane contains 74 direct or institutional records; Wild Rift contains 131 first-party or direct regional publisher records; and the Riot MMO register contains 16 direct records. First-party records establish what a publisher announced or documented, but do not independently settle disputed outcomes, motives, or performance.
Source availability and limits Source links are checked separately from the historical datasets. Eight unavailable VALORANT links use reviewed replacement records. Wild Rift S096 is omitted because no verified replacement was found. Riot MMO job sources S018 and S019 are marked retired because their URLs now redirect. A listed source can still move or change later.
