This paper proposes six approaches to library research serendipity. Coincidence assumes that a researcher inevita bly will find something useful. Prevenient grace accounts for the prior organization of information as a means toward serendipity. Synchronicity proposes the existence of hidden patterns and unknown forces aiding the researcher. Perse verance maintains that thorough researchers are likely to encounter serendipity. Altamirage assumes that unique be haviors can cause serendipity. Sagacity is a pragmatic and applied approach. It is conceded that serendipity carries a research stigma. Nevertheless, serendipity can be better understood and experienced more frequently.
