If you haven’t checked out the Just an Art Librarian blog, it is a great day-in-the-life account of an art librarian at a “medium sized library in a regional museum.”
There is an interesting post about where they’re at in their career. They ponder their ability to make career decisions in the current climate and their ability to even have the option to change. I think many solo librarians have the same concerns in similar situations. As a solo librarian within a design firm, I know I did.
