Apparently you've thrown up your hands at a Google search and can't find my source. Stop using your pro-Lincoln search engine.
My source is The American Annual Cyclopedia and Register of Important Events of the Year 1864, pages 393 and 394. It was published in 1866. The newspapers are listed in their Freedom of the Press section along with whether the papers were mobbed, suppressed, threatened, etc.
On the web this book is one of the Google books where they show some of the content. Google used to show both pages of the newspaper list -- they did when I found it. They now only show page 393, but not page 394.
I'll let you look at the causes of the various newspaper problems on page 393 in the link above. Here are the causes listed on page 394:
Union, Louisiana, Mo., Destroyed March 6, 1864.
St. Mary’s Gazette, Leonardtown, Ind., warned April 12, 1862. (rb note: I didn't include this one in my posted list because of date and possible location errors. The date must be 1864. Also, there was a St. Mary’s Gazette, Leonardtown, MD that started publication in 1863 -- I suspect that this was the warned paper.)
Picayune, New Orleans. (rb note: Appleton's didn't list what happened here in 1864. The Picayune had trouble more than once. In 1862 their publication was discontinued by good old Union General "Beast" Butler because of criticism of army officers. The Picayune's office, presses, books, and papers were "sequestered" by the army on the 1862 occasion. I don't know how long this continued, but the publishers and editors had to swear allegiance per "Beast" in the Official Records.)
Courier, New Orleans, suppressed May 23, 1864, and editors banished for republishing the bogus proclamation received via Cairo. The order was never revoked.
Metropolitan Record, New York, circulation forbidden at the West, March 25, 1864.
Transcript, Baltimore, Md., suppressed May 18, 1864, for publishing a dispatch saying the loss of the Army of the Potomac was not less than seventy thousand, and crediting it to the Associated Press.
Democrat, Cambridge, Md., suppressed September 9, 1864.
Metropolitan Record. (rb note: This paper appeared twice in the Appleton's list. Possibly an error or maybe it got dumped on twice in 1864. I only included it once in my posted list.)
Freeman’s Journal, burned at Nashville, September 12, 1864.
Democrat, Gallatin County, Ill., editors seized and imprisoned August 19, 1864.
Crisis, Columbus, O., editor seized and imprisoned May 10, 1864. (rb note: This paper was also listed on page 393 for a different suppression, I only included the paper once in my list.)
Register, Wheeling, Va., editors seized, paper suppressed July 20, 1864. (rb note: Apparently the name West Virginia hadn't taken root at this point.)
Journal, Belfast, Me., editor seized August 1864.
News, Memphis, Tenn., suppressed July 1864.
Bulletin, Baltimore, Md., suppressed July, 1864.
Gazette, Parkersburg, Va., editor seized by General Hunter, July 27, 1864. (rb note: I left this one out. Hunter destroyed 1,000 homes/farms in Virginia -- I figured that he had enough blemish on his record.)
Kentucky, June, 1864, all Democratic papers excluded the State.
All Democratic newspapers excluded from Memphis (except the Missouri Republican) September 16, 1864. (rb note: I left this restriction out of my list.)
On Sept 30th, the "Loyalist" at Baltimore was discontinued by order of General Wallace, and on November 29th, the "True Presbyterian" at Louisville, by order of Gen. Burbridge.
The annual Appleton Cyclopedia volumes were each perhaps three inches thick. They are filled with lots of facts about the war and various statistics. I checked out the volumes for 1861, 1862, 1863, 1864, and 1865 from a library. I now have copies of the Freedom of the Press sections of each volume.
I confess I can't honestly say I tried that hard.
