Is there a website where one can find stock business presentations?

A lot of companies reinvent the wheel and create lots of similar presentations and documents around topics like Sarbanes Oxley, cost allocations, project governance, etc.

I’m sure that many corporate internal functions like Corporate Finance, HR, and IT have common issues, and need to communicate similar concepts to their employees and customers and they create documents and presentations to communicate those concepts.

Is there a website you can go where people have contributed some of these documents and presentations so you don’t have to start from scratch (even if its fee or subscription based)? I know there are professional groups, management consulting firms, or roundtable groups companies like Gartner, etc. that will sell you content and documents, but I’m wondering if there are any sites where the contributors are experts from different companies in the various internal corporate functions. Maybe where there is some incentive for contributing good content, and companies pay to use that content.

Thanks.

There have been no responses, so let me rephrase my question a bit…

Are there any websites that have documents and presentations that can be tailored and re-used by a corporate shared services function (IT, HR, Finance, etc.)?
