famous book endings

Can anyone identify this ending of a (famous) book or novel? and more importantly give a (searchable) site where I could find others? “So we beat on, boats against the current, borne back ceaselessly into the past.”

Thank you for any help.

It’s from The Great Gatsby by F. Scotts Fitzgereld I believe.

Here’s the second part to your question:

A great site with many summaries and such of great books is http://www.novelguide.com

Thank you for all of you help that you have given me. Please give any other helpful sites that could be of service to me, in this situation.

Thank you!

A complementary site to that one might be Bibliomania.
It is not guided directly to fiction, but under the “Research” category it has a number of reference works.
