It's like a personal/curated library. I don't see what's wrong with that. Whenever I start thinking about some article or other I vaguely remember and want to re-read it, but can't find it again without substantial effort, I wish I'd been more fastidious about saving and archiving that article.
You see it best in how Luhmann used the Zettelkasten system, where ideas and resources are linked to topics that he wanted to think and write about.
