Flashbacks

These were published more recently, but take place before Harry's first appearance in the comics

Short about Harry's childhood and Norman's failings as a father. One of the best depictions of their relationship, in my opinion

Nice Things from Amazing Spider-Man Extra! #3

Gwen-centric miniseries set during her time in high school and giving some insight on her and Harry's longlasting friendship

Giant Size Gwen Stacy

From introduction to deathbed

Watch Harry evolve from goofy background character to Peter's most important narrative foil!

First establishing of Harry's character and his dynamics with other key personages such as Peter and Norman

TASM63 #31, #34, #39, #40

Further development of all aforementioned things. The highs and lows of Peter and Harry's life as roommates. Daddy issues. Romantic drama. Drug addiction subplot. Anything you could ask

TASM63 #46, #47, #53, #54, #57, #59, #60, #61, #62, #63, #66, #74, #82, #95, #96, #98, #105, #110, #118

The storyline that changed everything

TASM63 #119, #120, #121, #122

Harry grows increasingly suspicious and paranoid around Peter following his father's death

TASM63 #123, #124, #126, #127, #129, #134, #135

Now... here's a disclaimer for the following issues: Despite the aforementioned buildup being very well executed, the result is not exactly so and has more to do with giving the Goblin as a concept another hurrah, rather than delving into Harry's character. In fact I'd even argue they're out of character for Harry, as his behavior in them is just cartoonishly diabolical and in stark contrast to both his previously established personality and subsequent depictions of his Goblin. So yeah, these issues are technically important to the grander picture of what is happening with Harry and why, but don't expect insight lol

Harry's back and his friends are more than happy to welcome him. He even moves in with Flash

TASM63 #151, #152, #153

Harry and Liz Allan enter a romance and quickly move on to engagement. He is also seen seeking psychiatric treatment

TASM63 #156, #157, #163, #166, #167

The happiness was not to last: Liz' stepbrother, Mark Raxton aka the Molten Man stirs up trouble, and she leaves the city in the aftermath. Harry seeks fault within himself and appears to be on his way to going green again – but is all as it seems?

TASM63 #172, #173, #174, #175, #179, #180

Harry and Liz have settled into the suburbs. In come more Molten Man and more insecurities!

TSSM76 #63

A mysterious foe known as the Hobgoblin has been attacking the company Harry inherited from his father and even blackmailing him with Norman's secret identity. During this troubled time, Liz and Harry are also having a baby

TASM63 #239, #244, TSSM76 #85, TASM63 #249, #250, #251, #260, #261, #263, TSSM76 #146, WOSM85 #47, TASM63 #312, TSSM76 #147

Molten Man, take three – this time with a wholesome twist

WOSM85 #61, #62

Harry briefly attempts to turn the Green Goblin into a superhero

WOSM85 #66, #67

The final Green Goblin Jr Saga – an absolute Must Read. If I could recommend just one Harry storyline, it would definitely be this one

Post OMD Revival/"Clone Harry"

Full disclosure, I don't read much Post OMD Spider-Man. One day I might venture into it despite my gripes and add more to this section. Until then: I'd sort of be amiss not to include these two at the very least in a Harry Osborn reading list, even if recent nonsensical twists have revealed Post OMD Harry to have been a clone all along

Harry and Peter's reunion

Amazing Spider-Man Family #4

Harry cutting ties with his father. While I think this story could have been improved in numerous ways, watching Harry leave Norman behind is still pretty satisfying and I enjoy the way his relationship with Peter is portrayed in this
