Here's a chunk of the answer...

If what I do makes it just a little easier to find something or to join up the dots, then it's been worth it.  It may only be a tiny part of the universe of books, but for TMLers at least it's a part of us!

(Curious that I came across this just as I'm half way through writimg a little adventure thats a response to the burning (or not) of the Library at Alexandria.)

(Or perhaps it's not that curious.  Maybe it's all around.  On the radio just this afternoon they were paying tribute to Deirdre la Faye who died last month)

Perhaps more useful would be https://en.m.wikipedia.org/wiki/Deirdre_Le_Faye as the BBC may not work outside the UK.  Not sure.

Apparently her love (and excellence) of spending every day working in Jane Austen archives and research, seeking out new snippets of information etc. was unparalleled and a terrific contribution to knowledge.

Maybe one day my obituary might say something similar as a response to the question above.

Well, I can dream.
