for these sorts of items, I use binders with folders that have holes punched in them. each folder holds as many articles as i can stuff in there, and each folder is labeled, then each notebook is labelled.
my binders, which are part of my "books" in storage in the US, usually have to do with yoga. I prefer to go by topic such as "Asana, Jnana, Bhakti, Prana" and so on. Inside, I'll have folders such as "hips, spine, feet, organ systems," or "vedanta, tantra, sikhism," etc. inside there, i keep articles by date.
Then, the binders were kept on their respective shelf, near the yoga books that I have and also use as a reference.
