Abstract:

Generally, the 'year of first publication of the work' refers to the year in which the work (such as an instruction manual) was first distributed to the public. So, a manual written and distributed companywide in 1998 should obviously contain 1998 in the copyright notice. That's the easy example! But what about your question: What happens when the manual is revised? Interestingly, the Copyright Act doesn't directly say. But the commonly accepted practice is to include multiple years in the copyright notice, indicating the various years in which various material in the overall work was first published.
