I would start by saying that your requirement is a little too broad. Yes, indeed SharePoint is a great (greatest if you ask me!) Enterprise Content Management tool (Records Management, Document Management and Web Content Management - all accompagned by a lot of Business Intelligence, Social, Workflows and extreme extensibility by some of the richest API on the market - surpasses .NET all together). But, in your case you would need to formalize what exactly are you looking for, because the way I see it digitizing existing content is your main concern (if you only have paper version of your content) - and this simply leads to the biggest question, every single ECM will have for starters - "How would you manage the in-flow of content?".
Practically, this means scannning, clasifying, tagging, etc. Then, the actual business continuity, plus proper architecture, etc. - do not go in without help, and only go in after you did your homework - map out your requirements to the lowest detail possible, and ask solution providers for the Pros/Cons on other technologies - you need to consider what infrastructure you have, and what IT strategies are already in place!
Already, some case studies on MSDN/TechNET for schools already adopting SharePoint - http://technet.microsoft.com/en-us/library/hh285756(v=office.14).aspx or http://technet.microsoft.com/en-us/library/dd335971(v=office.14).aspx
