A series of seven books is called an Heptalogy. The terms septology or septet are also used sometimes.
It seems that Harry Potter and the Deathly Hallows was the last installment in the main series. Jo has also published The Tales of Beedle the Bard, Fantastic Beasts and Where to Find Them, and Quidditch Through the Ages. As of now, no more books in the septology are planned.In total, there are 7 Potter books that are part of the series and 3 supplement books.
The Septimus Heap series consists of seven books, ranging in length from around 80,000 to over 150,000 words per book. In total, all seven books in the series amount to several hundred thousand words.
They all have different names. The first series is called the Original Series, the second is called The New Prophecy, and the third The Power of Three. Erin Hunter is coming out with a new series called the Omen of the Stars. There is only one book out yet in that series which is called The Fourth Apprentice. I think you're talking about a series as in trilogy, saga, or quintet. I don't know the name of anything other than that, but I just wanted to clear that up.
