It's one thing to find resources that speak to your design challenges. It's a trickier thing to determine if the webpage is useful for your purposes.
This page provides some strategies and questions you can use to evaluate the resources you find.
Remember, source evaluation is not a checklist! A source that is appropriate for one use might not be appropriate for another. Always keep in mind the type of information you need, and the reasons you need it.
Additional resources on evaluating sources can be found on the Library's comprehensive Evaluating Sources guide.
