Scheffler's Firefly pendant is inside a wrecked fishing boat at the start of The Suburbs, in the Sewers section. It belonged to Josh Scheffler.

Shipping Manifest
The Shipping Manifest is a sailor's note at the Mission Hill Pier docks. After you vault the wall down among Robert's patrolling men, go right to the railing above the water; it lies by a fishing net behind a blue trash bin.

Singularity, issue 14 and the final Savage Starlight comic, sits on the driver's seat of a broken-down truck in the woods during the Jackson epilogue.
Siphon Hose
The Siphon Hose is waiting in Joel's backpack when the Pittsburgh chapter begins, so you collect it without doing anything.

Smoke: Chemistry is a training manual in the control room of the hydroelectric dam in Tommy's Dam. Smoke bomb clouds last 10 seconds longer once you have it.
Smoke: Shaping
Smoke: Shaping is a training manual inside a shiv-locked shed in Lakeside Resort. It makes smoke bomb clouds last 20 seconds longer.

To Get to the Other Side! is a joke book Ellie carries, an automatic artifact sitting in her backpack at the start of Lakeside Resort. It shows up in the Artifacts menu as soon as you play as her.
Tourists Manifest
The Tourists Manifest lies on an overturned cart in the garage with two dead bodies, early in the Alone and Forsaken section of Pittsburgh.
Trading note
