The internet is far too "entropic" to trust bookmarks alone. This has been a clear failing of the web since the 1990s. I've literally been downloading pages since then to have a local image. I've written various native code tools to extract text, index that and then markup the files with keywords and then create a local search engine back. SO MUCH is shadow-edited, deleted or lost. It's foolish to rely on ANYTHING online for more than a year or even less. If it matters you must have a full archive. When PDFs are referenced (e.g. scientific papers - I have 1000s of COVID papers), I download those and index them. This is also why I never rely on e-books - I order a hard copy because in 20-100 years, it will ONLY be the paper version that will still be around.
