One thing I have had to do during my records retention and information management project is lots and lots of research. Here are some of my favorite go-to sources.

AIIM.org:  

This site is chock-full of information and provides frequent up to date content via expert blogs and webinars from vendors and industry professionals alike. AIIM isn't specific to records management.  It combines the overlapping worlds of records management and enterprise content management into information management. If you read through a blog entry, be sure to visit the comments as well; this is where you’ll find the witty banter.

ARMA.org:

Another great online resource, this one focusing more on records management principles. ARMA is closely tied with the Institute of Certified Records Management (ICRM) Professionals and has oodles of study materials for the CRM Certification exam.  Even if you’re not interested in the certification, ARMA has some great training materials and road show downloads that you can use to get your records management message out to your user community.

Canadian General Standards Board: Electronic Records as Documentary Evidence:

The Canadian Government Standard for electronic records.  If you’re not sure if your electronic records will stand up in a Canadian court this is the document for you.  Anyone who wants to ensure that their recorded information in their IT systems is trustworthy, reliable and authentic should use this standards document as their guide.

CANLII.org:

This is where you will find all the legal regulations, citations and legislation in Canada. Companies need to really know their business to weed through this stuff. Once you get the hang of it CANLII is an awesome resource for all your legal questions. A word of caution, where a citation is open to interpretation seek internal and / or external legal advice from the professionals.

US Code of Federal Regulations and the United States Code via the US Government Printing Offices Federal Digital System (FDsys):

For Canadian companies with cross-border business in the US this resource is essentially the US de facto legal resource; the equivalent to CANLII.

I have used many more resources while researching my current records retention and information management project.  These are the sources that I go to pretty regularly; almost on a daily basis.  I'm curious to know what others have had experience with.
