Book of Kells

I'd say yes.
The Actual Book of Kells is in a closed case and open to one page, which changes and may not be open to a really decorative page the day you are there. The exhibit, and the library above were both more interesting to me.

Just noticed you said the library is closed. In that case, I wouldn't bother.

According to the Trinity College ticket website the Long Room is still open. Ticket prices have been reduced 15% while the Book of Kells is off display. https://www.tcd.ie/visitors/book-of-kells/tickets-information/?panel=tickets

Thanks for the feedback - the Long Room and the exhibition are open with just a replica book in place of the original. It sounds like the exhibit and Long Room would be worth the visit even if the actual book is not on display and there is a small discount.

Any idea when the real Book of Kells will be back on display?

I thought the Long Room was far more impressive than the Book of Kell’s so I’d say go for it.

“Any idea when the real Book of Kells will be back on display?”

The website says March 2020. I have no idea Whether that means March 1 or March 31.

I don’t think it is worth the time when the Book of Kells is there............

We will be in Dublin in mid-March and have a tour of Trinity College, the library and Book of Kells scheduled for March 19th so we're really hoping it will be back on display by that point. As mentioned by a previous poster our tour details mention "November to early March" for the replacement version.

Agree with other posters.....while the Book of Kells is, of course, an important piece of history, shuffling through to look at one page is somewhat underwhelming. The informational exhibits are well done, and the Long Room was one of the highlights of our visit. Go.

I have begun to feel that I may leave the Book of Kells off the list for the one full day in May touring Dublin that we have after reading comments here. Also, been trying to get tickets online at Trinity College site and it will not let me select a date. Tried the date we want and then just tried other random dates...no luck. Anyone else have issues buying tickets there? Does the Trinity College tour include the library’s long room?

It looks like there is a different procedure since I visited in 2016, but you still get tickets in person on arrival according to their page:
https://www.tcd.ie/visitors/tours/

It also says the tour and the Book of Kells/ Long Room are separate prices.

Edited to add:
I just did a dummy Book of Kells booking and it let me choose a date and get to checkout.

I agree it's definitely worth the visit to see the exhibition and the Long Room. The Book of Kells is neat, but I enjoyed the Long Room much more.

This time we're not seeing the Book of Kells. We saw it 1977 when it was on a nationwide tour of the US at Philadelphia Museum of Art with the rest of the National Museum collection. Also, saw it at Trinity 3 x. At this point it's sort of underwhelming. I bought the expensive complete Book of Kells life-size facsimile ($$$$$) used on e-Bay for less than $50 ! Awesome. Also, I just read that the ENTIRE B of K is now on-line !

I'm going to agree with others in saying the Long Room was more impressive than the book.
