Week 3: Research Questions

1. In English class we were told to organize our references and use scholarly resources, therefore is there a filtering option that can identify the different types of resources or organize according to the types of bridges?
2. How else is it possible to identify if a resource is scholarly and deals with bridges without having to look at the content?
3. How would we research about different Truss structures within the truss topic. For example which is the most efficient structure for our project's purpose?
