the last active Jewish temple in Newark has a museum. They may be able to help you. Sorry, I don't recall the name or a contact name.
TSTI also has a museum. I am sure any of the local synagogues would be interested.
If any of them are in Yiddish, please donate to the Yiddish Book Center. I believe they will even come to pick them up.

Also, please consider donating to YIVO.
Thank you for not discarding these books.
