I sometimes look through:
http://www.largeprintbooks.evjoy.com/
http://www.doubledaylargeprint.com/
http://www.largeprintbooks.com/
To see what new/newer books might be out at the library...
hmm there is no filter in their search to isolate large print books
ah ok you search for large print (DOH) my local library has "Your search for "large print" found 3919 titles"
