The Association for Library Service to Children (ALSC) has updated and released three Summer Reading lists. The lists are full of book titles to keep children engaged in reading throughout the summer. 
Lists are available for K-8 students. Each is available to download for free on the ALSC website in color and black and white.  Lists can be customized to include library information, summer hours and summer reading programs for children before making copies available to schools and patrons. The lists are available at: http://www.ala.org/alsc/2014-summer-reading-list.
“Summer reading helps prevent the summer slide that affects many children each year,” said Starr LaTronica, ALSC president. “By encouraging children to stay engaged in reading throughout the summer at home and at their library they will be more prepared for the next school year.”

The Summer Reading List was compiled and annotated by ALSC’s Quicklists Consulting Committee and School-Age Programs and Services Committee through a 2013 Carnegie Whitney Grant funded by the American Library Association Publishing Committee. The 2014 list was updated by ALSC’s Quicklists Consulting Committee.

NOTE:  It’s not intuitive to get these to print well, but I figured out a method and made a little screencast of myself doing it, in case you need some help.
