Librarianship is an underrated career. Most librarians love helping patrons solve their problems and, in the process, learning new things. Librarians may also go on shopping sprees, deciding which books and online resources to buy. They may even get to put on performances, like children's puppet shows, and run other programs, like book discussion groups for elders. On top of it all, librarians' work environment is usually pleasant and the work hours reasonable, although you may have to work nights and/or weekends
The job market for special librarians (see below) is good but is sluggish for public and school librarians. Nevertheless, persistent sleuthing—that key attribute of librarians—should enable good candidates to prevail.
That effort to land a job will be well worth it if you're well suited to the profession: love the idea of helping people dig up information, are committed to being objective—helping people gain multiple perspectives on issues—and will remain inspired by the awareness that librarians are among our society's most empowering people.
In the interest of objectivity, this week a post about the difficult job market in academic libraries at ACRLog has generated lots of comments from the trenches. The effort to land a job is not to be taken lightly.
