If it makes you feel better, this is a long standing problem of document and source loss. As just a small historical example from a fellow, but very early, note taker and practitioner of the ars excerpendi (art of excerpting):

Presumed to have been written in the fifth century Stobaeus compiled an extensive two volume manuscript commonly known as The Anthologies of excerpts containing 1,430 poetry and prose quotations of classical ancient works from Greece and Rome of which only 315 original sources are still extant in the 21st century.[1] Large portions of our knowledge of many famous classical texts and plays are the result of his notes. Perhaps your notes will one day serve as the only references to famous documents of our time?

Often for digital copies of things, I'll use a browser bookmarklet to quickly save archive copies of pages to the Internet Archive as I'm excerpting or annotating them. See https://help.archive.org/help/save-pages-in-the-wayback-machine/ for some ways of doing this.

Fleeting notes are similar to the sorts of things one would have traditionally kept in a waste book.

Francesco Sacchini recommended the use of two notebooks:

“Not unlike attentive merchants... [who] keep two books, one small, the other large: the first you would call adversaria or a daybook (ephemerides), the second an account book (calendarium) and ledger (codex).” —Francesco Sacchini "Chapter 13". De ratione libros cum profectu legendi libellus. Wurzburg. p. 91. (1614).

(See also Blair, Ann M. (2004). "Note taking as an art of transmission". Critical Inquiry. 31 (1): 91. doi:10.1086/427303.)

The root word ephemeral in this context is highly suggestive of the use and function of fleeting notes.

The Latin word "ephemerides" can also be translated as "newspaper", useful for only a short period of time.

Recall also that in a general sense Cicero contrasted the short-lived memoranda of the merchant with the more carefully kept account book designed as a permanent record.

(Not sure if I had this in my notes already from other reading, but adding again just in case.)

If this special issue of Ephemera ever comes out (I have been keeping an eye out for it but nothing as yet) it might be highly relevant for this discussion: http://www.ephemerajournal.org/content/labour-academia-0 Back issues of Ephemera do cover topics related to this discussion too though, so might be a relevant resource anyway (and OA!)
