Bookmarks are a very dangerous way to save your research. Resources do not stay on the internet forever, and you may lose that perfect article you were referring to when it is taken down a year or even a week from now.

There are a lot of tools that you can use to clip pages for later in a notes database, but i have found notes apps with their own proprietary databases to be unreliable in the long run. The best solution for me has been saving to a PDF or text/md file in the file system.

And of course you can save these in your client, project, or book file, or you can organize into folders by research topic in case you should need to find them for another project down the line.
