Hello how may I help you? Hi. How do I use this service? You just ask a question. About books, or can I also ask about magazines and websites? I am a librarian bot so books, yes, magazines, maybe, websites no. Great. I was trying to find the most recent issue of JACS. I'm not sure what JACS is, there is nothing in my database by that name. Oh, could you try Journal of the American Chemical Society? I don't see that either,is this a magazine or a book? Scientific journal. I'm sorry but I am not equipped to help with that type of material. Okay.
