(I really need to stop joining all these secret groups!)

I worked at a library. Depending on the job, librarian could still fit, even if the person did not have a specialized degree.

M-W defines librarian as:

a specialist in the care or management of a library

The key term here is 'specialist'. People who serve a specialized role in the library, like doing research or managing a department, would commonly be called librarians. Similarly, the head of a school library would also be a librarian, regardless of their degree.

Someone like me, whose primary job was to put books back on the shelves and man the check out desk, would more commonly be called a library assistant or simply library staff.
