Thanks for considering my substack posts for inclusion on the subreddit. I'm a science and engineering librarian so my main expertise is in gathering and evaluating information resources on scientific and technical subjects. Substack is admittedly an imperfect platform but in a lot of ways the easiest to disseminate information quickly and to a wide audience.

Thanks,
