(2) John Linneball's answer to How many act books do you need? - Quora (Click the link to see the original Quora post).
I’d recommend a few - the official ACT guide. You can buy it used; for example, see
The Official ACT Prep Guide
But I’d recommend it new, just so you don’t see other people’s answers written in it. Trust me, even when people SAY a book is in “like new” “never been used,” etc., it it’s been written in. You can probably get this used for free on Craigslist or similar sites, or simply by asking families whose kids are done with their ACT prep.
Manhattan Prep’s 5 lb book ACT questions is also very good for practice.
You can also use Barron’s ACT books, although their problems are considerably harder than those you’ll find on the real ACT. But it’s great practice to prepare you for the hardest ACT problems.
Here’s a link to Barron’s ACT books:

What is the difference between the different editions of Barron's Act? What is the difference between the different editions of Barron's Act?
I also recommend Barron’s SAT for ACT prep, since the ACT “English” and the SAT “Writing” sections are identical - they’re formatted identically, and the questions are meant to be answered identically. I like Barron’s SAT’s concise and easy-to-understand review of English grammar, diction, and punctuation better than Barron’s ACT review of the same topics.
Other than that, you can find older ACT practice tests here:
