Instead, more precisely, I'm looking for "When you're interested in or reading about a specific data structure, and wish to implement it in your programming language of choice, where would you typically go for a reference implementation?"

I've been wanting to beef up my overall knowledge of data structures (breadth and depth), and the best way I know how is to "do it". So this means I will want to locate (preferably) canonical implementations of data structures. From the searching I've done so far, I was unable to locate an authoritative list anywhere.

Of course I'm sure with enough searching I will come across implementations in libraries scattered across the web. For most things this is probably ok, but given that data structures are such a fundamental part of CS it seems it would be nice to have a single source (if only links to other resources) where I could go knowing I will be directed to what the community considers the defacto implementation of a given data structure.

GitHub seems it would be a perfect place to start compiling such a list.

Also once that list is compiled I imagine another logical step would be to start annotating those in something like [http://genius.com/]

I of course have come across this: http://en.wikipedia.org/wiki/List_of_data_structures

But it really only gives me a good long list of data structures I may like to write implementations for.
