Librarians can actually work in variety of fields, not just traditional libraries (knowledge managers, law librarians, researchers in variety of venues etc), but you need masters degree in Library studies (or library sciences) and informational technology (or similar).

If you work in the library but aren’t a qualified librarian, you will be an assistant with a low salary. You’d be back to square one. Low pay. The only way to survive on low pay is to always work two jobs and it could get rough.

What are your degrees in and could those lead to more gainful employment? Not saying to get rich but be able to pay your bills. Is there a career center in the university you graduated from? Could they help? Narrow down your career options? There might be something out there that you maybe don’t know about. Some jobs just aren’t advertised widely
