She’s been keeping a low profile since her Sin City cocaine arrest, but Paris Hilton ventured out to do some shopping on a rainy day in West Hollywood, California on Monday (October 4).

The hotel heiress browsed around at Book Soup, where she picked up a little reading material including "29 Gifts: How a Month of Giving Can Change Your Life" before heading over to an office building in Beverly Hills.

Tweeting about the literary-nurturing outing, Miss Hilton wrote, "Just bought a lot of great books at Bool Soup. I love reading. You can learn so much from a well written book."

Also trying to help out her sister Nicky’s jewelry making endeavors, Paris wrote, "RT – Hey everyone, check out my sister’s hot new jewely. Nicky Hilton jewelry Available Now!"
