After presenting my beat board and animatic to my peers and tutors the general feedback was that the story idea is liked but it needs definite tweaking, mainly with the ending. If the librarian is depressed at his Fathers death then why not push the boundaries of this and make the ending the end of the characters life too? He could be swallowed by the library, become part of a book or kill himself in his confusion and grief. After having to explain the story I found it difficult to explain the beginning section so will most likely cut this or try something different.

Time for tweaking...
 
Here's my first (serious) animatic following the latest beat board that I published here recently:
 
I have been trying to write a narrative that will accompany the images on screen as I feel that my current storyboard needs it for the story to make sense. Currently I imagine the narrator to be someone that is not the Librarian, but someone who the Librarian can hear in his on screen world and perhaps his actions are determined at points by what the narrator is saying, or looks disgruntled if he doesn't quite agree with how his story is being told.
Books are windows on the world, they are our teachers, our companions, but most importantly they are storytellers. Some stories have mythical creatures clawing their way out of the pages; some contain romance and a happily ever after; some hold adventure on the high seas. But like the sea, life is unpredictable and this particular story is not a happy one.

This is a story that its owner would prefer to keep locked away.

On saying that, it would be preferred by this librarian if all books and stories could be shut away. For grief has turned him into a hollow shell of the man he once was.

…Well at least his imagination still works.

And does this story have a happily ever after? Only time will tell, for it is still being written…

 
Finally pinned down a synopsis for the Librarian, so here it is:
We follow the Librarian, a man warped and twisted from the severe pain he experiences when he loses his beloved father to old age.  His personality is not what you would typically expect from a person who is supposed to be a lover of books, for this melancholic character despises stories, especially those with a happy ending. Having grown up loving the old fairy tales his father used to read him from the books in their library, he undergoes an extreme reversal of feelings towards them after his father is gone as they painfully remind him of what he has lost. With his emotions causing havoc, these fairy tales become menacing, in his mind a happily ever after is a thing of fiction; inheriting the library that he once loved feels like a graveyard of painful reminders of what he has lost, and our Librarian is sure those horrid books and stories are out to get him. Our Librarian is set on a journey that will confront his grief through the fiction that haunts him, and as his audience we will hear his very own story, just don’t expect a happily ever after. So come, sit close and listen to the tale of the Librarian.

 
I've finally managed to pull a working story out of my brain and put it into beat board format.
The idea is that the librarian is reading a book which is narrating stories and images to him, and then tells a bit of his own tragic story which he gets angry about so slams the book shut. He is then seen in his library being tormented by the books (all in his head) and after a brief pause attempts another read at his own story.
