Puer Dux -
Some Loeb Volumes can be found on Google Book. The trick is that they must show a print date no later than the early 1920s, so that their copyright has expired. Another trick is that these early volumes frequently have a publisher of "G. P. Putnam & Sons"--that is one thing you will want to enter into the 'publisher' box on the 'advanced search'. You also only want to select 'full view books' on your search. These Loeb volumes below are not published by Harvard but G.P. Putnam & Sons. Besides the volumes below, other Loeb volumes I have found & downloaded from Google Book are by Apollodorus, Apostolic Faters, Appian's Roman History, Clement of Alexandria, Euripides, Herodotus, Hesiod, Menander, Plato Euthyphro, Plato Theatetus, Thucydides, Aristophanes, and Xenophon. I have found many if not most of these by
going to the advanced search page and simply typing in one thing, 'G.P. Putnam & Sons' in the publisher box. Then I had to go through many pages to pick out the Loeb volumes. The Loeb volumes will always have a distinctive little sqare logo in the tiny picture of the book's first page shown on the search results.
Here is one of the Loeb volumes available on Google Book:
Xenophon Anabasis books 4- 7 http://books.google.com/books?id=vFA8t__AArcC&pg=PP9&dq=Xenophon+Anabasis+Books+IV-VII
Aeschines Speeches --I have found him to be a step up in difficulty from Xenophon, but still understandable.
Plato -Theateus and Sophist-- http://books.google.com/books?id=f18MAAAAIAAJ&dq=inpublisher:G.P.+inpublisher:Putnam%27s+inpublisher:Sons&num=100
Herodotus Book 5 http://books.google.com/books?id=Qh8MAAAAIAAJ&pg=PA2&dq=Herodotus&num=100#PPA1,M1
