Members of Apple’s Developer Connection are being offered a hugely extensive collection of useful video resources for purchase and download.

The ADC Video Collection for IT includes video of all the conference sessions held at the Worldwide Developers Conference last year.

These 100 videos cover the gamut of what developers may need to know in order to build applications for the Mac.

Apple describes the collection so: “Experts discuss using Apple technologies from configuring network infrastructures, through integrating Mac IT solutions in an existing heterogeneous environment. IT developers will find topics on designing and coding products with the frameworks and tools available in Mac OS X.

The collection costs $499.
