More of a general question:

This detailing job has more info than I can keep in my head, 

Especially info used like once a year, 

Ended up making a folder for every supplier/company to contain their specific info, (150 suppliers),

Then have a word document with heaps of headings, subheadings, subsubheadings etc, with pics showing specific things, every different manufacturing situation etc,

How does everyone sort their brain?

Need like a wikipedia within the company, that the programmers can use and share, 

Any recommendations?
