If I may, the field is oversaturated with library school grads and what few positions are occasionally available have a lot of competition. I’d suggest she get work in a library as soon as possible. Volunteer early and often. Making contacts. The more she’s already in the library before she gets the degree, the more likely she will be to find a job. In my class of 30+, only 5-6 found work in the field. And they all networked like hell and had years of directly-related experience before going to library school. Researching, getting published, giving talks and presentations also help.
