The cover of the book is the first to check. Looks good? But remember – a book cannot be judged only by its cover.
Go through the summary given on the back cover or inside flap. Does the book sound like something you would enjoy?
Skim the text, specially look for illustrations. Good pictures will help you understand the topic better for non-fiction books and it will be an added attraction for stories and novels. Here your age also matters!
Check the New Arrivals Rack in the library or the bookstore.
Look on the recently returned bookshelf. You will get some good choices. It's a good guest that the books taken by someone else may be a good one.
Get suggestions from your librarian, who would be glad to help you and may be knowing your likes and dislikes!
Ask the recommendations of your friends and ofcourse, discuss the books you have read.
Your teachers are the best sources. Read the books they might have discussed in the class.
Check the credentials of the authors. If you liked a book by an author, most probably you would like his other works too!
Go for books published by well-known publishers. They select their books and authors judiciously. So you can rely on them.
Browse through the library shelves. Something will catch your eye.
Read the book reviews on Newspaper, Magazines and Internet.
A Word of Caution
"No good book, or good thing of any kind, shows its best face at first"
So, do not judge a book by reading just the first few pages.
