The search form
The search form on the right is of course the quickest and easiest way of finding that particular quote. Your keyword is being searched in the quote, the author, the original foreign text (if available) and the source (if available).
You can also use logical operators link NOT, OR and AND. When you search for "Nietzsche NOT life" you will get all quotations of Nietzsche not containing the word Life.
Probably you have favorite authors and here it is easy to find famous quotes of them. On the Authors page we have grouped all authors on last name so it is easy to find that particular author. But you can also browse the Popular authors of famous authors with the most quotations.
We also have the profession, nationality and the years in which they lived of over a thousand authors. This provides a sometimes essential context to the quote but it also allows you to browse quotations from for example American politicians or English scientists. To see all categories and be able to browse quotes using this, go the Authors per category page.
A few popular authors
When you are looking for a specific quote on a subject it is best to just search for that subject. This can be done with the search form, but you can also see many popular subjects on the Subjects page. Also, at the bottom of each page is a tag cloud with recent used search terms.
