Always type an author's name with the last name first.
Example: If you want to find books by Charles Dickens, type Dickens, Charles in the text box.
Choose a title search if you know the full title or the beginning of the title of the book.
To find the book "One hundred years of solitude" with a title search, you could type the entire title or the even just the first few words of the title (One hundred or One hundred years). Do not choose a title search if you do not know the beginning of the title of the book.
NOTE: If you do not know the full title of the book, and the words you know are not from the beginning of the title, search for the book with a keyword search. So, for example, you could type words from the middle or end of the title (like "years of solitude" or only "solitude").
