look at lines 30-32; lines 50-53; then about line 56 to the end of the poem.
Realizing that although one is getting older and may die (or is dying) that it is not too late to seek new places, knowledge, and accomplishments. It is amazing (to me at least) how this poem (at least part of it) does reflect fondly on a life of satisfying accomplishments and at the same time reminds us to never stop seeking more from life.

Michelle suggested "Ulysses Unyielding + the greek word for books" or I thought maybe "Unyielding Ulysses" or "Gray Spirit Yearning Booksellers" or "Utmost Bound Books" or "Beyond the Sunset Books"
