http://www.archive.org has both reprints of old out-of-copyright books and a lot of government publications, such as http://www.archive.org/details/nasa_techdocs and http://www.archive.org/details/NISTJournalofResearch .
http://www.sciencebooksonline.info/
http://www.intechopen.com/books
http://www.e-booksdirectory.com/listing.php?category=1 for science books http://www.e-booksdirectory.com/listing.php?category=3 for math
