Ikari’s glasses are on top of the chest of drawers.
There are also German medical books (psychology, genetics, etc.) with several pieces of paper shoved between the pages.
Azathoth: Interesting that they're specifically identified as German - Rei can read it? There might have been potential for Asuka-related shenanigans with that down the road if Yuko Miyamura could actually speak the language.
thewayneiac: Yes, Rei reads German. The book she's reading when Asuka tries to befriend/annoy her in Ep. 09 is in German.
Dr. Nick: Books about psychology and genetics? Is Rei trying to learn about her origins?
NemZ: Could be a sign that she’s strongly predisposed to following in Yui’s footsteps academically. Heck, they might even actually be from Yui’s library, given to Rei as a gift.
