On my present on-going projects, i had to place the breadcrumbs in a strategic way and make it look good.

Here I have complied a list of links which I visited to help me keep track of them and remember on which project I used it for.

Useful search results with keywords as ”UI patterns for breadcrumbs” on Live and Google search engines.

• Welie.com (Patterns in Interaction Design) which also has links to more Literature on research of breadcrumbs (also Nielson)
• UI-patterns.com (User Interface Design Pattern Library)
• The Diemen Repository of Interaction Design Patterns which also has links to other Pattern libraries such as Jennifer Tidwell, etc
