I remember renting "A night to remember" after seeing "Titanic" in theatres. I think I prefer that to Cameron's production. I just bought the 1996 and 2012 TV movie versions on DVD and will watch them back to back. I only saw a few episodes of "Titanic: Blood and Steel".

To the OP:
I
strongly
recommend the following books:
Titanic: An Illustrated History
by Don Lynch and Ken Marshall(which was actually James Cameron's inspiration to make his movie)
Titanic: End of a Dream
by Wyn Craig Wade
The Titanic Conspiracy
by Robin Gardner and Dan van der vat(even if you don't agree with their main thesisthat the Titanic was really her sister ship Olympic sunk on purpose as part of a massive insurance fraud orchestrated by White Star, the authors do discuss other aspects of the story in fascinating and absorbing detail)
Titanic: A Night Remembered
by Stephanie Barczewski
Titanic: A Fresh Look At the Evidence by a Former Inspector of Marine Accidents
by John Lang
Titanic: Everything Was Against Us
by Simon Angel
And finally,
Titanic And the Indifferent Stranger: The Complete Story of the Titanic and the Californian
by Paul Lee.

For some reason I just saw this for the first time. I wish I had seen it years ago.

One of the most fascinating books I've read on it is The Ship That Stood Still by Leslie Reade, about the role of the Californian.

Also, The Odyssey of C.H. Lightoller by Patrick Stenson.

There's nothing like getting the story in the words of the survivors. Those have been compiled in a number of collectionshere's one.

Col. Archibald Gracie's book is one of the most staggering ever writtenit's a little tedious to read cover-to-cover, because he compiles affidavits from at least one person from each lifeboat, so it's sort of a lot of the same story over and over again, but it's such a wealth of invaluable information, it's one of the most priceless books ever written on the disaster. Lawrence Beesley's book is pretty captivating too.

Any other books on the subject that you would recommend? I know this board isn't too active but any recommendations are appreciated
If you enjoyed Walter Lord's
A Night to Remember
, you will want to read his later book,
The Night Lives On
which has further information on the tragedy and its participants. It seems to be out of print, but is easily available use from Amazon, as I found here:
http://www.amazon.com/Night-Lives-Stories-Unsinkable-Ship-Titanic-ebook/dp/B0078X73NY/ref=sr_1_6?s=books&ie=UTF8&qid=1443977713&sr=1-6&keywords=walter+lord
..or possibly from your public library (where I found it).
The Titanic community is an active and sometimes scrappy one, so any book will have its critics. But, as enjoyable reads, for starters I recommend Dr. Robert Ballard's own book about finding the
Titanic
:
http://www.amazon.com/The-Discovery-Titanic-Robert-Ballard/dp/0446671746
I also enjoyed Daniel Butler's
Unsinkable:
http://www.amazon.com/Unsinkable-Full-Story-RMS-Titanic/dp/0306820986/ref=sr_1_1?s=books&ie=UTF8&qid=1443978355&sr=1-1&keywords=daniel+butler+unsinkable
..which pretty much covers similar ground as Walter Lord's book, but with some new information and insights. It is very well written and engaging though critics have found factual errors (this is true of pretty well all Titanic books).
John Maxtone-Graham also has a couple of interesting books on the topic. He's an expert on a number of the famous liners, and he published the memoirs of Violet Jessop, the stewardess who survived both the
Titanic
and
Britannic
tragedies, and has some amazing stories to tell.
Her book published with him is here:
http://www.amazon.com/Titanic-Survivor-Memoirs-Violet-Stewardess/dp/1840151005/ref=sr_1_4?s=books&ie=UTF8&qid=1443978209&sr=1-4&keywords=maxtone+graham+titanic
and his recent book on
Titanic
is here:
http://www.amazon.com/Titanic-Tragedy-Liner-Paperback-Common/dp/B00FBBWADS/ref=sr_1_13?s=books&ie=UTF8&qid=1443978692&sr=1-13&keywords=maxtone+graham+titanic
There's a wealth of material online as well.

Well, there are definitely a lot of books on the subject.
Maybe you could search online on
Encyclopedia Titanica
for any particular recommendations.
