The smallest collection of card catalogs is near the librarian’s information desk in the Social Science/Philosophy/Religion department on lower level three. It is rarely used and usually only by librarians. It contains hundreds of cards that reflect some of the most commonly asked questions of the department librarians. Most of the departments on the lower levels have similar small collections. Card catalog behind the reference desk on lower level three, photo credit: Tina Lernø

I find it very tiring haha. As I said in another comment, processing a single chapter can take me a full day or two. However, I keep reminding myself that I would rather spend a day processing a chapter well, and have literature notes to serve me a lifetime (potentially, at least), rather than reading a chapter in two hours and not remember a single thing the next day. When I REALLY need a reminder of this, I just look at my "Backlog" folder which contains old "notes" that are now pretty much useless: I didn't use a reference manager consistently during my first two years of PhD so there are a lot of citations which are unreliable; I didn't really summarise texts, I only read them and highlighted; I didn't use the cloud for a long time, so I lost a lot of notes; and I didn't have Obsidian, so a lot of my notes are just contained within the context of the place I read them, rather than being connected. Seeing three years worth of useless materials, and knowing that I read a couple hundred of articles/chapters but I have nothing to show for it, that makes me more patient when writing my literature notes now. However I also find it very exciting that I can future-proof some of my notes. I feel like I'm working for my future self.
