How many journals can one follow at the same time? I have been following 7 journals at the same time for may be about 10 years now. 4 of them are relatively unpopular and publish may be about 50 papers per year, so they are easy to follow, 1 has 100+ papers so it sometimes requires an effort to read about everything they publish but the other 2 are very popular and publish biweekly full issues with dozens of papers, so it is painful to follow them and I need to look at their webpages to see what is new almost every day. However, I'm interested in a field where I always need to look for papers outside of it and have to browse many journals irregularly to find possibly interesting information. That means I browse through dozens of journals irregularly and have to look through literally thousands of papers. And, oh God, it takes its toll. But the REAL problem is that my requirements only get broader with time, so I now can't just keep on. I think there are really too many journals and too many papers in them to browse through and I can't even manage to read through all the titles of all the papers that could potentially interest me, let alone read the abstracts.

This is why I would like to try to find someone who has similar problems and ask him/her how does s/he manage to solve them, e.g. what does it take to browse the maximum number of journals possible as far as search optimization, number of journals covered and time are concerned? Is it possible to cover a wide field and follow everything it happens in it so you could be aware of the new papers published in dozens of journals or is this simply impossible? I want to know how far can I get and how much time would the effort consume, so, if you could share with me your experience I would be very thankful.

Thank you very much!
Use a content manager and subscribe to the journals' RSS feeds.

I currently follow ~30 journals and a few blogs (this number changes dynamically as I remove some journals and include others) using feedly, which is a RSS reader that is very user-friendly and has apps for both Android and iOS. The software automatically fetches new content from the journals' latest issues and makes them available to me in real time. My daily feed is usually comprised of ~50 new papers every day. I devote 15-30 minutes of every morning to going through it--except on some weekdays when journals like Nature and Science release an entire issue. Going through the feed includes reading all titles, identifying potentially relevant papers, reading their abstract and saving them to my Mendeley library. Some people keep track of new papers through Mendeley alone, though I prefer feedly.
