To cold to go out? Care to curl up by the crackling monitor with a good online book to read? Google has a mind boggling number of public domain books scanned so you can read from the the "original" and often out of print copies. (Some you can even download)
 
If these are not to your interest, go to Google /advanced/book search and input the topic of your choice. (Hint,.. go for those marked "full view". Watch on the right if it has a download box to click, otherwise just read!)
