If there is a commonly reoccurring need for a particular solution, there is a great probability that someone has - by now - solved that need and has finished the legwork involved in researching and constructing something that resolves it.
At the very least, you will find documentation on general solutions to related problems that will enable you to gain insight on best practices, effective techniques, and real-world examples on the thing you are creating.
A design pattern refers to a reusable and applicable solution to general real-world problems. For example, a solution for navigating around a website is site navigation (a list of links that point to different sections of the site), a solution for displaying content in a compact space are module tabs.

Welie.com has an interaction design pattern library maintained by Martijn van Welie, a Ph. D. graduate in Human Computer Interaction who now works as an Interaction Design Senior Consultant for Philips Design. The library features a ton of design patterns involving various site tasks such as navigating around a site, searching a site, and basic interactions such as slideshows. Each pattern follows a specific format: (1) the problem, (2) the solution, (3) when to use the pattern, (4) why you should use the design pattern, and (5) examples of the pattern in use.
Created and maintained by Matthew Smith and Chris Pollock, Pattern Tap is a gallery of popular web-based User Interface components and design patterns such as slideshows and breadcrumbs. Pattern Tap allows users to create their own sets, and they now have over 7,000 user sets. There’s plenty of inspiration to be gained at Pattern Tap.
This design gallery focuses on common web page components such as navigation as well as popular design trends such as Grid layouts. design|snips has over 30 categories so that you can easily find the design pattern/trend that you’re interested in. What’s more, users are allowed to rate each design featured in the gallery so that you can see what the overall consensus is with regards to the effectiveness and appeal of a design being shown.
The UI Pattern Factory
The UI Pattern Factory is a UI design library and gallery. What’s great at UIPF is that they sometimes share videos in each entry to improve the description of design problems and solutions. Entries are further enhanced by user-submitted examples of the pattern, which they archive in their Flickr group: UIPatternFactory.com.
