Over a year ago I mentioned Rachel M. Shain’s thesis on the preverb εἰς, but I did not at that time mention that it can be downloaded for free. To get a copy, go to the OhioLINK ETD Center. Thanks to Mike Aubrey (ΕΝ ΕΦΕΣΩ) for pointing out this link back in 2010. I’m not sure why I didn’t include it at that time.
For my earlier comment about adding this thesis to the Special Topics page at Greek-Language.com, click here.
