Right, so I noticed that my long-term memory(which was really poor to begin with) is declining. This is...not good.
I have really good short-term memory. Not in a "memorize word-by-word" way (I am ridiculously poor at that), but in a "read something once and I can already tell you all the basic things about it" kind of way. But when it comes to long-term, or even a term of a few months, I'm pretty poor at it. If you'd ask me to tell you the basic plot lines of all the books I've read this year I'd probably couldn't even remember all the titles. Character names escape me as soon as I'm done with it. I can't remember anything about movies I saw more than a year ago. And, worst of all, I can't remember anything that I've studied.
Say I spent a few months in spring memorizing tankas. I'd gotten to about 30, most of them memorized without any issues. I stopped practicing and I struggle to recall even one now. Not just the whole tanka, I've already forgotten the first lines (which should be too basic to forget). Over the years I've read numerous things on history, and when I needed them for school I could basically recite all the events of a period (minus years since they never stick) without much difficulty. Not to mention all the details on literary currents, their impact, and what not. After a few months, nothing stays. I can't even recall all the plots that I wrote about in my thesis 2 months ago. Even some of the titles escape me. Not to mention authors.
This is particularly problematic since I'm pursuing an academic career, where being able to recite fancy quotes, ideologies and terms is pretty important. But I forget everything about them easily, and I can't spend my life cramming every day so as to remember.
Is there any way to actually improve your long-term memory?

. One thing I noticed about RTK, for example, was that I would forget the stories really quickly, whereas the images stuck with me far better. It might be because I've never used them much (one trick I do use when trying to memorize is tapping a beat to a string of words, which does stick quite well). How do you make mnemonics when reading a book, anyway?
