you can access PDFs (and other formats) of ALL versions of the above publication (which is still produced by the AES today) from 1890 to 1998. Big deal you may think! But I've downloaded every PDF and, with some free PDF searching software (PDF Xchange view from http://www.tracker-software.com/product/downloads/), am able to search for certain terms (such as "masseyi") across the whole lot in a minute or so. There is some absolutely superb material buried in these publications and, in combination with a good search mechanism, is extremely valuable for anyone wanting to do some research.
Also - if anyone has any other sources of "open access" to scientific journals of a Lepidoptera nature, please post here
