Fingers flipping through pages while the eyes scan the columns, till what you're searching for pops out, can be quicker for the researcher trained in using print. A digital search requires that you spell what you're looking for accurately. I would hold races between students and myself to find infornation. I'd use print, they'd use digital. Invariably, I won. Not that I'm smarter but if you can't spell, you can't find digitally.

We do subscribe to the online edition of Encyclopedia Britannica. Just this week, I noted I couldn't easily find what I was looking for in the database. We don't have a print set of the Encyclopedia Britannica in our collection for me to compare the ease of finding the information. We do have a circulating set of World Book. I was able to find 'daylight savings time' in the D volume. Sometimes the print encyclopedia is just what you need for quick answers.
