I worked in an academic library. I did a two year course at library school, part of a London polytechnical college.
There was shelving, cataloguing, interlibrary loans, dealing with fines for overdue books, putting books aside reserved by students and staff, or books on reading lists, lending out laptops, selling stationery, restocking same, filling up photocopier, displaying new books added to stock., cataloguing new books and theses., ( books now have a catalogue record from the Library of Congress included.) I was the archivist, and had a project to list old documents, and add photographs of the college to a database. I also arranged small exhibitions of archival material.
When I first started, (1973) we made up lots of journals for binging, packed them up, wrote out orders by hand, did it all in reverse when they came back from the binders, labelled them. By the time I retired nearly everything was online. (2010). In the 70s and 80s we did a weekly run, dleivering and collecting books and journals on interlibrary loan from other libraries in London. H.K.Lewis's medical bookshop and library in Gower Steet was like stepping back in time and had it's own special smell of books and central heating, especailly on a winter afternoon. My day started with a 10 minute walk to unlock all the bookcases in the library, and finished with me locking them up again. When I retired, almost everything was computerised, and the old bookcases had given way to computers and open metal shelving., and Lewis's has closed and the building is part of University College London.
