Getting that I am almost done with the first year and am starting to study for finals/put away books and re-organize the bookshelf... I decided to weigh the material sitting on my bookshelf.
About ~140 lbs.
Note: This is just the text books, coursepacks... and does not count the many volumes of notes that were taken independent of this stack of books, or the stacks of notecards I use to memorize things. Also, does not include the clinical skills supplies or anatomy lab supplies.
