I've read that the tactile aspects of physical books help a lot. This is very anecdotal as I kind find the particular reference I was thinking of.

But personally I can recall the specific size, weight, smell and texture of physical books I've read. It adds context and helps distinguish books as independent physical entities which (I believe) helps with recall. On the other hand digital books have begun to blend together for me.

Again very anecdotal.
