How to organize research sources without losing them

Every piece of research reaches the same afternoon, whether it is a doctoral thesis or a second-year essay due on Friday. You are writing, you need the paper that made the point you are about to make, and you cannot find it. You remember the argument, the approximate colour of the PDF and roughly when you read it. What you do not have is the link, the title or the author, and thirty minutes later you are re-searching Google Scholar for something you already found in March.

The problem is almost never that you did not save the source. It is that you saved it into the wrong pile, next to things that are not sources. Fixing that takes a container made only for sources. We build Moodmarks for exactly that job, and it shows up near the end; the method itself works with any tool that meets the requirements below.

Three piles, not one

Studying and researching produce three kinds of material, and they want three different homes. This is as true for a university course as for a thesis or a work report; only the size changes.

Sources are things other people made: papers, articles, datasets, websites, interviews, a thread that summarised a debate well. They have an origin and a link. You do not edit them.

Notes are what you think about the sources: summaries, objections, the sentence you want to steal the structure of. They are yours and they change.

Drafts are the thing you are producing. They change constantly.

Most systems fail because they put all three in one place. A folder of PDFs with your notes scribbled in the margins is sources and notes fused, so you cannot search either. A Notion page with links pasted between paragraphs of your own thinking is the same fusion the other way round. Neither is wrong as a place to think; both are wrong as a place to find.

Keep the piles apart and each one gets simpler. Drafts go in whatever you write in. Notes go in whatever you think in. Sources need a container of their own, and that container has a short list of requirements.

What the sources container has to do

It has to accept anything with a link from anywhere, in one tap: a paper from a browser, an article from Twitter, a PDF, a podcast episode, a site you found on your phone at a bus stop.

It has to keep the sources for one project together and apart from the sources of every other project, because "the paper about attention" means something different in your thesis than in your side project.

It has to let you attach a line of context to each source at the moment of saving, because that line is what you will search for later.

And it has to be searchable across everything, from the first day, without a paywall between you and your own material.

For citation-heavy academic work, Zotero does this well and generates the bibliography too, which is worth the setup if you are writing a thesis. For everything short of that, and for the research that happens on a phone between other things, a board-based bookmark manager is lighter and faster to feed. The method below works with either.

The method

One board per project. Not per topic, per project. The thesis is a board. The final essay for a course is a board, and so is the group presentation you got stuck coordinating. The article you are writing for a magazine is a board. The comparison you are doing before buying a car is, honestly, also a board. A project has an end, and when it ends the board becomes an archive you can still search.

Save the source, not the fact. Save the paper, not a screenshot of the paragraph. Screenshots lose the link, and a source without a link is a memory, not a source. If you need the paragraph, the note can hold it; the source keeps the link.

One line of context per source, at save time. "Counter-argument to chapter 2" or "the dataset for the second graph" or "quote for the intro". Ten seconds now saves the thirty-minute afternoon later. This is the whole trick and it is the step people skip.

Search before you re-search. When you need something, search your board first. If it is not there, then go to Scholar. Half the time it is there and you had forgotten you already did the work.

Where notes and drafts go

Anywhere you like, as long as it is not the sources board. If you think in Obsidian, think there and paste the link to the source. If you write in Google Docs, write there. The sources board is not trying to be your second brain for thinking; it is the shelf your thinking pulls from. We wrote about the broader system, boards as projects, in how to build a second brain on your iPhone.

Keeping the scope this narrow is what makes it work. The board does one thing: it holds every source for one project, with a link and a line of context, and it is searchable. It does not summarise, annotate or write. Those jobs have better tools, and mixing them in is how the pile becomes unsearchable again.

A note on the phone

A surprising amount of research happens away from the desk. The reference a professor drops in class, the paper someone mentions at lunch, the article in a newsletter you read on the train, the site you find while looking for something else. If saving those takes more than a tap, they do not get saved, and they are often the best ones.

That is why the container should live on your phone as much as your laptop. Moodmarks is built around exactly that: one board per project, save from any app through the share sheet, add the line of context, search everything. The free plan covers five boards, which is enough for a thesis, a couple of courses and something of your own. If your work is closer to journalism than to academia, the same system is described from that angle in our roundup of bookmark managers.

Moodmarks is free on the App Store. Start with the project you are in the middle of; the next source you find is the first item.
