Access to occupation records on Ancestry.com will be free now until September 5, 2016 at 11:59 p.m. ET (they do require registration for a free temporary Ancestry account). After the free access period ends, you will only be able to view the occupation records using an Ancestry paid membership. You may view a full list of occupation records via the search page (they’re including federal and state censuses in the list!).
Remember, you can access Ancestry Library Edition for free any time at Central Library or any of our branches!
