My children, even the teenagers, re-read these books every year. We put them away at the beginning of Epiphany and only pull them out at the beginning of Advent, and the family is always overjoyed to see them again. On St. Nicholas' Day every year, I give them a new Christmas book. For those of you in the United States, you should be able to find these at your local libraries. For those overseas, it may be hard to access as easily. I would be glad to give you my top recommendations based on your ages of children if you can only purchase a couple.
HAPPY READING!

Polacco, Patricia
Great current children’s author who illustrates her own books; appeals to a broad range of children; celebrates family, miracle, and heritage. I do not like all of her books because they express attitudes or moral choices with which I disagree, but the ones listed below are excellent.
