This curation comes with a price: a library carousel with too many articles and minutes go by to find the one you're searching for. So, I've solved this problem by creating "Teacher Groups" or "TG" for short.
When I'm searching for a specific article about science, I will usually get distracted by another articles. I would usually add it to the library, return to the main screen, and have to start the process all over.
To solve my multi-tasking dilemma, I add the article directly to that Teacher Group (TG) shelf. This allows me to keep curating until my heart's content.
The neat thing is once something is shared to a group shelf, it stays there until you "unshare" it. There's no delete button, so you can rest assured, it isn't going anywhere unless you choose.
This means, when the article/book is in my library carousel, I can delete it to free up space and reduce clutter. When I need the article again, I just return to its group book shelf where it was shared.
