Is the Paris Review considered a series?

[Evie]

Good evening, everyone!

I came across two copies of The Paris Review, #145 and #155, at a book sale. When I came on here and went looking, I realized that they're not being grouped together… but are they considered a series? Here are some examples I've found:

And some of them also include the season in their title:

On the whole, it's all very inconsistent and certainly a project if they are to be treated as a series. How do you even go about organizing something like this?
