this is where i have just gotten very used to telling people give me one second i have that information and pulling out my phone to open up my notesrecords  its a little unconventional but generally surprisingly well tolerated as long as i can get the info within a minute  especially in academia this has been invaluable and ends up in ways making me more trustworthy in casual conversations because i dont just state facts as i remember them i always have my source for them as well
