Take a look at design view of a table, one of the "Data Type" options is OLE object. Here you can set up a field for each document combined with other fields to allow you to categorize.
After creating the field I right clicked on the cell and selected Insert object, then chose create from file to select the word document. If you check off "link" I think changes will be reflected back to the original but if you leave it unchecked you can make changes from Access.
