If you want to get the inside scoop on the variety and diversity of LIS positions available to you, then you should definitely network and conduct informational interviews. This is a critically important job search strategy — and you can take advantage of it whether you are actively conducting a job search or not. Staying connected and keeping a pulse on the job market and on your field of interest gives you an advantage. Research shows that only 10 to 15 percent of available jobs are ever advertised. That means the rest of the job openings are in the hidden job market — the market of networking and informational interviewing.
