a map of the earth we use latitude and longitude lines. This greatly assists in finding an accurate location. The same is done in the sky. We draw imaginary lines across the sky. Those line running north and south are called RA, or Right Ascension. Lines running east and west are DEC, or declination. If you look at any detailed map of the sky you'll see these marked on sky maps. I suggest you go to a library or bookstore near you and see if any books are offered with good sky maps. A couple of especially good star atlases for beginners are listed below. I doubt you'll find either at a library or any local bookstores, but each can be ordered. The Edmund is especially recommended for a beginner, and besides the star maps is crammed with much useful information. It's beautifully written by the late Sam Brown in the 1950s. In the late 1970s it was updated by Terence Dickinson, and again in the late 1990s. I still refer to mine and I've been observing more years than I care to remember.
