Reddit mentions of The Ultimate Scholarship Book 2020: Billions of Dollars in Scholarships, Grants and Prizes

You can find the book here and I agree, it's a great scholarship resource. Many libraries also have it.

You can apply for non-institutional aid (the stuff on, for example, scholarships.com) right now, but know that scholarships you get right now could lessen how much need-based financial aid you get. So if you got a $500 scholarship, your future school might just lessen your need-based aid by $500, too. I don’t think it subtracts from merit aid, though, so if you aren’t expecting much based on your FAFSA or can get more from outside scholarships than you’d get need-based aid, your best bet will be scholarships.com, unigo.com, or books like this one
