Theft = taking something that doesn't belong to you.
Robbery = taking something off of someone's person, with or without violence or violent threats.
Burglary = breaking into someone's home or office with the intent to commit a crime, usually theft
All of the above are forms of 'stealing' (if the burglar ends up stealing while there)
EXAMPLES:
If you steal someone's car and the person isn't there, it's theft. If you steal someone's car, and the person is standing 10 feet away, that's theft. If you steal someone's car and that person is in the driver's seat, and you force that person out, or tell that person to get out, that's robbery, e.g. car jacking.
If you see someone's wallet fall out of his pants, and you grab it, and run, that's theft. If you take it out of the person's pocket or bag, that is theft. If you tell someone to give you his wallet from his pocket or bag, that is robbery.
In other words, both robbery and theft are forms of 'stealing'.
You cannot 'rob' a thing. You can only rob a person.
You cannot 'steal' a person. You can only steal a thing. (Note: stealing a person is known as... kidnapping.
So the example above you share from the Washington Post is poor grammar.
This is wrong:
She'll work in the New York Public Library, despite the fact that she once had her purse robbed there. (Washington Post; 1979)
This is correct:
She'll work in the New York Public Library, despite the fact that she once had her purse stolen via robbery there.
Or:
She'll work in the New York Public Library, despite the fact that she once was robbed there.
Or:
She'll work in the New York Public Library, despite the fact that she once had her purse stolen there.
Also note: You usually don't say, "I'll work in the library" unless you are in the same building, and the library is one of the areas within that building. If you are outside the library, and you're talking about your place of employment, which is the NY Public Library, you use 'at', i.e. "I'll work at the NY Public Library".
