IMPORTANT UPDATE: SOME LINKS HAVE CHANGED. THE MAIN ARCHIVE PAGE HAS MOVED. I WILL UPDATE THE DESCRIPTION BELOW AS TIME ALLOWS.
The New Jersey Division of Archives and Records Management gets five stars from me (here they are guys...★★★★★) for a terrific website, with a lot of digital content, great family history databases, and a clear, sensible, user-friendly arrangement.
There are several databases of census and vital records dating back to Colonial times:
There's even a very intriguing file of Legal Name Changes, 1847-1947, a wonderful family history resource, and something that more states should consider posting online. Many of the name changes look to be attempts at Anglicization, like the 1919 change from Giovanni Di Guglielmo to John Williams.
Other NJ databases, military and civil, are equally unusual:
For all of the NJ Archives databases, you can easily access the information through name searches, or by searching on other parameters (county, city, regiment, and so on). You can also order copies of the original records, although these images are not available online.
The other major digital component of the NJ Archives are what they call the Imaged Collections, 4,600 images from the photograph and manuscript collections. While this collection is not as robust or as user-friendly as the databases, it is still a worthy addition to online archives. The topics covered here are:
There is also a collection of Documentary Treasures, including NJ Constitutions, materials relating to the US Constitution, select NJ government documents, and Revolutionary War materials, including the original Treaty of Paris, which formally ended the Revolutionary War, and is certainly worth a look.
Before leaving the Garden State, we should pay a visit to New Jersey Digital Collections archives at the NJ State Library. These are harder to find, but still, well worth the effort.
A very diverse set of documents are available here, as PDFs (two of them, the Registers of Revolutionary War and Civil War soldiers, were the basis for the NJ Archives databases by the same names):
