Have you tried our Your Quotations Page feature? If you sign up and log in, you can store a number of your favorite quotations on your own page. Just click the [+] icon next to any quotation on any page to add it to your page.
You were originally limited to 100 quotations on your page, but last week we increased the limit to 1000 by popular request.
We will also be enhancing this feature by the end of September to allow you to share your collected quotations with friends and others—stay tuned.
