(Are you looking at a scan somewhere?)
Every villager is listed with the name at the top left, in bold black, followed by the birthday (next to which is the astrological sign) and then the gender and personality type are given in the green bar. His or her coffee preferences are indicated by the letter next to the Brewster icon. If the villager is new to NL, it will say "NEW!" in the pink bubble, otherwise it will indicate which game the villager first made his or her appearance in. Following that, there are two pink smileys that indicate, firstly, preferred theme (such as modern or crazy) and secondly, preferred colour. Below that, the blue smiley indicates what theme the villager dislikes (such as sporty or gorgeous). (If you send a villager something that is disliked in a letter, it will not help your relationship, nor are you likely to get a present back.) The shirt icon identifies what the villager wears. (Which you can actually see in the villager's snapshot.) After that you get a snapshot of the interior of his house, then his picture and quote.
