I have bunch of textbooks, and a lot of lecture notes and notes from colleagues, all in PDF format. What is a good way to classify, manage, store, and read these PDF files? I am trying calibre-web, but it seems difficult to find applications to connect to it.
Benefit of data managers: Tags for easier searching and grouping, grouping that is folder agnostic, easily choosing a thumbnail, and in text focused ones you can usually search the content of the files from one location and easily look through the results for the correct one, etc.
