If a record or an image you want isn't available online at their site, FamilySearch will tell you where you might find it.
I've just spent an hour viewing these links below. Some contain a FAVORITE sentence of mine:
"To view a digital version of this item, click here." Ahh, access!

My Dad served in Korea during the war. Years ago we ordered and received his military file from NARA (National Archives) and also his father's records from the Great War.
I thought I had exhausted the many online military databases available regarding my Grandfather's service in World War I. But upon signing on to FamilySearch today, it suggested a record I hadn't seen before.
It was a simple card showing his enlistment and discharge dates. Full legal name, address, DOB. Yes, I already knew those dates from other records, but hey! It's another source. Secondary proof! Proof I might obtain when learning of a distant cousin whose birth date is unknown.
An added bonus was seeing yet another (miss)spelling of Grandpa's middle name. A three-syllable word that I've not seen with any other person. This rendition appeared to be typed phonetically: Sulvenious. #SMH
It was a reminder to allow for misspellings when searching databases by keyword.
