If you take a few minutes to go to the John F Kennedy Library site on the internet you can read detailed information on the lengthy struggle required to design and construct this wonderful library and museum. It took longer to build this library than it did for us to put a man on the moon.
There is a wonderful picture in Wikipedia that shows the building at dusk with the huge flag that hangs in the glassed area clearly visible.
But before we start our tour a word of warning. Don't even think of driving in Boston. It looks like the roads were laid out along meandering cow paths. You can go in circles in this town. Not only is driving very difficult, but parking will cost you more than you can imagine. (Think in terms of $25 a day or more.)
But the public transit ("T") is fantastic. When I was there an all day pass was $14, which allowed unlimited use of the "T" (subway), city buses, and the many water taxis. Taking a train from a surrounding town 45 minutes away was also unbelievably inexpensive. Round trip was $11 (senior rate).
So just take the subway to the JFK station about 5 miles south of downtown Boston. A bus will pick you up and take you to the door of the museum. Connections are easy, quick and I think the best way to go.
The bus drops you at the main entrance to the library.
Looking up in the huge glass enclosed entrance you cannot help but see this wonderful flag. The pictures do not convey the immensity of the glass entrance, nor the size of this wonderful flag. 
My wife is the tiny figure at the bottom of the photo to the left. I have no idea how they wash all this glass!
As I stood looking up in the entrance way I realized there were workmen walking around on the glass ceiling. The odd looking blob in the center of the photo is one of the workmen and I had to use my telephoto to get this shot.
The layout of the museum is chronological and designed like many are today. You follow a meandering hallway around the building seeing the various displays. As I mentioned in my blog on the Clinton Library this one was not so much about how great Kennedy was but more about the national events while he was in charge and how he responded to them and inspired our nation to greatness.
Here is some technology history. The original set used for the nations first televised presidential debate. The black and white TV and "old" looking controls help us realize the changes in our country in the last 50 years.
This map shows the (blue) states that Kennedy won. He was elected president with 303 electoral votes to Nixon's 219. The popular vote was much closer at about 34 million each. with Kennedy getting only about 100,000 more than Nixon or about 1/10 of one percent.
This photo of the original 7 Gemini astronauts reminds us of Kennedy's leadership in our space program. His bold 1961 challenge to put a man on the moon by the end of the decade required our nations best minds to answer his call. Kennedy did not live to see men walking on the moon. 
The space exhibit reminds us of how far technology and space travel have advanced from a simple beginning. It also made me realize how much these early pioneers did with such limited tools and how quickly the problems of putting a man on the moon were solved. Many products we now take for granted were born of the necessity of the NASA program. WD-40, the simple hand held calculator, battery operated tools, smoke detectors, small battery powered vacuum cleaners, etc etc.
The library and museum show Kennedy's impact on the world as well as on space.
The commemorative stone above reflects England's feelings. They donated an Acre of English ground to the United States in memory of J.F.K. The Library contains many similar photos showing how nations honored the memory of JFK.
One of several photos the library has displayed shows the John F. Kennedy Museum in the Solomon Islands.
The dining room was a pleasant spot to eat in the Kennedy Library. Not only was the food good, but the view was wonderful. This is where I learned that my Midwestern accent did not properly pronounce "clam chowder". I had to repeat my order twice before the waitress smiled and said "Oh Clam Chaddah". Even in this commercial setting the Chaddah was very good.
Here Linda enjoys the view and a chance to eat lunch.
The Dining area was pleasant with the large windows.
Down town Boston from the dining room
Here is Kennedy's desk.
(John or Robert's ..can't remember which)
There was a very nice display of the "Cuban Missle Crisis" and a fuller story than you ever heard from the evening news. The events as they unfolded were fascinating and the displays help you grasp the world significance of what Kennedy did.
And from his inaugural address we find this:
Want to read more on Kennedy and his presidency? Start with a wonderful site that gives an annotated bibliography of each president. Here you will find comments about the various books written about Kennedy.
http://www.presidentprofiles.com/Kennedy-Bush/Kennedy-John-F.html
These are not hyped up "everything is wonderful" comments but useful comments to aid you in selecting books. Under a different presidents bibliography they make the following comment after giving title and author "..this other wise fine biography is flawed only because it was written by his best friend"
Visiting the JFK Library site will give you lots of additional interesting information
