What are good techniques or suggestions for people on verge of memory decline to better remember where to find a scientific material?
Personally when I read something in a book or in a paper or a website/blog (for example a particular proof of a theorem, a particular approach to a concept, a particular application of a result), I unconsciously assign it with the names of its authors.
When I would like to recall or to see that thing again, knowing the names of its authors is very helpful, since by knowing the name I can find the source very easily even if I have forgotten the title of the source.
This approach works if one has a relatively sharp memory. But as the memory starts to decline (for example by aging), sometimes recalling the author of a source could be difficult. When I forget the authors' name finding the source could be very difficult. Sometimes even with the help of search engines, I can not retrieve what I want.
Are there good techniques that people with limited memory use in order to better recall a scientific source?
