We reject the idea that it is impossible to “stay on top of the literature”. Scanning and reading papers is one of our most important and enjoyable responsibilities as scientists. The backstory is explained in an older post that editorializes on why this approach is superior to just leveraging twitter, relying on emailed tables of contents, or spending a lot of time organizing PDFs in apps like Mendeley. This page serves as a focused and updated “how to” guide on using RSS and efficiently scanning the literature.
We navigate the literature at different levels and must become comfortable with two things: 1) not progressing the vast majority of articles past each level and 2) abandoning an article in the middle of each level.
At each stage, aim to progess less than 20% of the articles to the next stage - said another way, aim to reject at least 80% of the articles! Your goal is to only save those that are interesting and to segregate those activities that can be done without much mental engagement (levels 1-2, can be easily done on your phone, for example) from those that require focus (generally 3 and 4 - and most certainly 5 require deeper concentration).
For example, it generally takes me less than a second to make a decision on whether a title is worth the “save for later” designation - and less than 20% pass that threshold! Of these papers I read the abstracts (5-10 seconds per paper) and decide to open the full article for less than 20%. I can read abstracts on my phone or my computer. If I’m on my computer, I will often go through the rest of the steps. If I’m on my phone, I simply unstar the ones I don’t want to read and leave the other ones stared to engage with the full text when I’m at my computer.
Of the papers I open to scan through the figures and headings, I decide that ~20% of the articles are actually worth reading (15-45 seconds per paper). Of the papers I read, I bail part way through most of them and read every word for about 20% of the papers (1-3 minutes when I bail, 3-15 minutes when I read the whole paper). Of those, I study about 20% of those papers by reading them multiple times and looking through references, thinking critically about the figures/controls, etc (20 minutes-2 hours per paper - only 1-2 papers per week get to this stage). Of the references I look up, I probably end up scanning 20%, reading 20% of that, etc. This allows me to engage with past literature and pick up on important papers I may have missed otherwise.
This strategy keeps me aware of what is being published and gives me a partial knowledge of what many of the papers look like, what kind of conclusions people are drawing, what techniques are emerging, etc. I think it helps me develop a broad knowledge of what is going on in the literature and allows me to focus on a small subset of papers to read deeply. Is the 80/20 number totally made up? Yes. Many weeks it might end up as 95/5 in some steps and 50/50 in others. It’s just a guideline that makes me very comfortable abandoning papers at any point in the process.
The intial filter of titles relies on RSS. There are many RSS readers. This guide focuses on Feedly, but there are others, such as The Old Reader that can also work.

This is not an exhuastive list, add journals, people, etc liberally. Once you get used to sorting through the literature every day, you will find that you do not get overwhelmed. You can always “amnesty” and start fresh at any time by clicking “mark all read” and starting again. RSS is wonderful!
Yes - but that presents more opportunities to actually read an important paper.
Separate reading titles, sorting abstracts, and reading papers into distinct tasks at distinct times
I scan through the titles from RSS feeds very quickly. I have a good RSS reader on my phone (Feedly’s native app) that syncs with Feedly’s web version. Whenever I am walking, I use the app to swipe through article titles and star the ones with interesting sounding abstracts. I generally sneak a peek at the author list too and save based on authors.
Similarly, when I’m on my computer, I scan through titles very quickly using keyboard shortcuts (
j for next,
k for previous) and save articles for later (keyboard shortcut
When I have small pockets of time (usually waiting for someone or sitting somewhere), I go into my saved folder (on the phone or computer) and read the abstracts. If I have a lot of time (more than 5 minutes) and am at my computer, I will open the interesting ones in the background (install this extension and then the keyboard shortcut is
This keeps the focus on the abstracts and doesn’t require touching the mouse or trackpad. I get into a rhythm of hitting
s to advance (, open) and unstar an article. If I’m on my phone or don’t have a lot of time, I just unstar the ones that no longer interest me.
When I have time (generally first thing in the AM and on weekends) - I open up background tabs for all the articles have survived in my saved folder and start scanning through them. I’m a fairly fast reader and have learned to get a lot out of scanning articles. I think this is an important skill to develop as a scientist.
