 Hi, I'm Waylin. I am an Yale intern at a portal branch of the San Francisco Public Library. You have probably heard of Kuvler or Levy, which are both online resources that allow you to access library collection without visiting the branch in person. But in fact, the library offers more than things like books or movies. Discover and Go is a service that provides free or low-cost tickets for attractions like museums and zoos. Thanks, I'll talk briefly about how to use it to reserve tickets for a popular location in San Francisco. From here on into this website, you can see the full list of attractions available for reservation today. However, popular attractions are usually not on the list. It is because all of the tickets for this day have been reserved. In which case, you can specify the attraction you want using the search feature. Say I want to go to the California Academy of Science. If I fail first, show first the way we offer. Here, click reserve. Follow the instruction on screen and you're good to go. Enjoy your visit.
