Reading the comments above, I think libraries are now seen as information centres rather than places to give access to books as they used to be. That’s the problem. The focus is on ‘information management’ , not actually knowing anything about literature. So proficiency in IT etc is seen as more important. I think that’s a great shame. Says it all about the way things are going.
Libraries have always been about information management rather than literature. It is just that now there are more varied ways of storing and accessing information.
When my Mum got her library qualifications the vast majority of information would have been in books, journals, maps, and other paper based sources with some microfiche.
Now computers are the dominant way of storing and accessing information. A huge amount of information that would have been on paper is on computer.
The librarian is the expert in storing and accessing information, not the expert in the content (although a subject specialist librarian might have a degree in their subject).
Literature is a teeny tiny part of what libraries do and general public libraries are a small sample of the typical work of a librarian. A much greater proportion of librarians work in specialist libraries, some public and some private. University libraries, school and college libraries, local studies libraries, private company libraries, subscription libraries, libraries associated with government departments, professional associations etc etc
Many librarians will specialise in a subject, things like medicine or law are very specialised but include no literature.
Sometimes subject specialist librarians will end up working in a more general setting because the skills are transferrable.
