Multiple Phonebook App?


Hi there, I'm new to the forum so hope I'm posting in the right place. I'm looking for a phone book app that allows for easily switching between multiple phone books. For example, I'd like a phone book for my own personal uses, one for work contacts, maybe even one for restaurant phone numbers, etc. I tried googling for something like this but haven't had any success. Any suggestions to do what I'm looking for?
