Them would be the correct pronoun for this sentence because books is plural and is an object, so its pronoun must be third person. The 3rd person plural pronoun in English is they, and its objective/accusative form (the form used when the item is the object of a verb) is them, so there's your answer.
Bilingualism is important to the community, in the world but especially to me. Bilingualism is important especially if you were to travel to a foreign country. It also helps you understand other cultures and why they do what they do in their daily lives. When you speak or say a simple sentence to someone who speaks another language, it lets them know that you care and respect them. Bilingualism helps you be closer and closer to the people around you and it lets you understand them better... it is also great to have that knowledge because you never know what might happen, you could move somewhere where people don't speak English or any other language you speak so you will have to learn something new which can be hard but if you already know a few phrases or words, then it will be a little bit easier for you.
