Ferenc,
Yes you can. Just get a copy of Writer's Market for the current year. In there you will find literary agents who represent your work. You'll need to write a query letter and make sure it's free of any errors of any kind. You may be asked to submit the first three chapters with your letter. It's important to follow the guidelines set down by the agency. It's also important to know what is called 'Industry Standard Format' when submitting your three chapters. You can find all this on the WWW, the library, or in your bookstore. Beware of agents who charge a reading fee. Usually they take the fee and turn down your manuscript.
Beware of vanity publishers as well if you desire to self-publish. They will publish anything and you get exactly what you send to them . . . errors and all. There is very little editing if any.
Good luck!
