In this guide you will find useful information regarding how you can use the library search tools to search and find information related to all aspects of design. For instance you will find relevant databases, journals and general search tips! For more subject specific databases check out the pages on product design and interaction design.
A good starting point is to use Libsearch in which you search simultaneously in almost all the library databases and the physical library (i.e paper books).
A search tool like Libsearch is very useful for interdisciplinary subjects such as design.
