Several years ago I came across a listing for the book The Black Box by Thelma Lientz and wanted to look it up before purchasing it. At the time there wasn't any information I could find on it and no other copies for sale. After doing some intense googling I found a link that led me to some information about the series this book was a part of. The link didn't take me to an actual site, but something like the data remains of an old site. The text was all jumbled together amid a giant wall of other text and html.
I copied the text, pasted it into a notepad .txt file, and sorted it out right. This .txt file has been an invaluable guide for this series as well as the series' it was divided into. I'm sure without it I could have figured it out myself through purchasing books in the series' and monitoring eBay listings but that would have taken time and money (also who knows if I would have ever figured out that The Phantom Town and Phantom Town Mystery, both by Carol Norton, are two separate books). This file also made it possible for me to create a series listing on goodreads which has helped others.
As I said I found this years ago and I'm not surprised that the data remains of the site seem to be gone now, at least I couldn't find it. It seems to only exist in my file now so I thought I would post it since I found it so helpful.
I want to be very clear, everything below this is not mine. I did not write it and I am not trying to take credit for it. If the original creator is brought to my attention I will, of course, credit them properly.
