Aeschylus: Select Bibliography

This is a select bibliography of scholarly works in English, largely monographs.
As was the case with Sophocles, I have seen many links to a bibliography of Aeschylus by the late Eugene Cotter, but the links are no longer working and I have not been able to find a working link for this bibliography. If any reader has it cached or downloaded I would appreciate a tip!
