From the Net:
His three full-length novels are hardly masterpieces; his crowning achievement is still the short story.
The Sun Also Rises
A Farewell to Arms
For Whom the Bell Tolls
To Have and Have Not
The Garden of Eden
Across the River and into the Trees
Islands in the Stream
Torrents of Spring
I get eight full length novels. For sure The Sun Also Rises, A Farewell to Arms, and For Whom the Bell Tolls are regarded as masterpieces, and they are all full-length novels.
Across the River and into the Trees was panned when it first came out, but it has since been regarded as a great book on a par with those three.
Same with The Garden of Eden. It was also panned mostly for the posthumous edit job, but it’s now regarded as one of the greats too.
And Islands in the Stream is also now regarded as on a part with the best.
So there are six great full-length novels.
Torrents in the Spring is no doubt a minor novel.
To Have and Have Not is generally seen as a minor work.
