I don't know if this will help you, but what we did for SQFregarding the registers was to create excel work sheets. They are like an index in that they list all the items for the register in the rows going down and the colums across the top lists all the different documents required for that item, for example raw materials, all the raw materials are listed down the side. Then across the top is the differnent required documents such as MSDS, Spec Sheet, GMO Statement, Kosher Cert, etc. What we did was list the date of the document in the column so we could easily see when it would be due to be updated. Also we made these clickable links so that if you want to view say a certain spec sheet, you click on the link in that cell and it takes you right to the information.
