sherry, vermouth, port, and madiera are fortified wines, like brandy, and will keep for a long time, corked and in a dark closet. a little sediment may settle, but it's not a problem. sherry and vermouth come in dry and sweet (cream), and port comes in tawny or ruby.
dry sherry is used in many cream sauces, some soups, some chinese cooking as a substitute for rice wine, and in some desert dishes. It will perk up an ala king or a tetrazini (noodles cream sauce chicken or tuna) cream sherry which is much sweeter, is used in cooking mainly for deserts.
as with all wine use in cooking, you want to add the wine in time for it to flavor and tenderize the food and also cook off the majority of the alcohol. adding wine at the last minute doesn't help much unless it's flambed.
wherever you buy wine you should be able to find sherry.
