a library of games-related interaction design patterns

a site that focuses on social media design and the patterns emerging in those types of apps

For those interesting in design patterns more specific to coding patterns.

this is a collection of patterns (in German) and done by a gentleman named Markus Drews' for his thesis project.

this site is kind of a mess but appears to have a wealth of examples to explore.

not a pattern library per se, but more a study in how not to do error messages and dialogues in web apps and rich client apps.

from the group description: For a publication (part of my thesis in communication design) on how we find, collect, evaluate and share information I am searching for images of „Everyday Information Architectures". The kind of images I am researching are those of personal design solutions for organizing and structuring everyday life and environment: bookshelves, movie-collections, mind-maps, workplaces, toolboxes, garages, photoboxes, filing cabinets etc.

New and innovative techniques of data visualization (InfoVis). Coolness, aesthetics and efficacy of visual representation methods. Screenshots of visualizations, diagrams, charts, ontologies, ...

This group is created for capturing user interface design trends and patterns NOT decorative patterns. Images not adhering to this description will be removed. Also, screenshots of home pages will be removed if they do not specifically illustrate the use of a user interface.

a collection of design solutions

Reuse, recycle, but don't reinvent the wheel unless necessary. by Brian Christiansen at UI Engineering. Via. This collection captures findings of consistent, unique or interesting interfaces and design flows from across the web.

a subsection (but QUITE important) of the Designing Web Interfaces site.

a wiki that accompanies the great book Ajax Design Patterns. As one would expect, this site focuses on design patterns related to Ajax and web applications. Quite comprehensive and technical documentation of the patterns.

last updated in 1999, this site appears to be Tidwell's site while doing her graduate work (she went on to write the seminal Designing Interfaces book). Still an amazingly well done and valuable resource on design patterns.

a comprehensive list of links to design patterns resources. Many great links to academic papers and theoretical information on design patterns.

Although this is no longer maintained, it remains a good resource for IxD design pattern resources. This page contains information about resources related to pattern languages for interaction design (of which user interface design is a subset), and a few links to more general papers that may be of use to interaction designers. I also include some links to organizational design patterns, which I find hard to disentangle from interaction design.

Alexander wrote the seminal book "A Pattern Language" in 1977 that promoted "patterns" as an approach in diverse fields, from architecture to city planning to business to design. Remains influential today.

A seemingly spottily maintained resource but interesting nevertheless. This site seems to promote the process of learning about and creating pattern libraries. You can find links to the following pattern-related resources: People, Events, Patterns, Publications, Tools and Other Resources

A pattern library that focuses on open-source design patterns (whatever those are). Has categories for Content Management, Information Organization, Input Forms, Navigation. A good resource and interesting site to explore if one is interested in a well-documented project.
