Hi Michelle,
The text that was referred to me when I started researching ciphers which is most relevant is:
"Die anfänge der modern diplomatischen geheimschrift: Beiträge zur geschichte der italienischen kryptographie des xv jahrhunderts" by Aloys Meister.
This can be downloaded online for free.
I translated this using Google translate, so that I could get a idea of what it says.
It is the best starting point for learning about ciphers from the time of the Voynich. Of course there is plenty that isn't in this book and the book selects a small number of ciphers from each particular source archive, so you don't get a complete picture. Nevertheless it is by far the best text on the subject.
I will probably post a list here of all the ciphers I know of from the time of the Voynich when I find the time.
The DECODE people have the resources to go around different archives photographing ciphers, which I don't. However the time frame for ciphers that I am interested in much more limited than theirs.
Hopefully I will be able to persuade them to return to the Vatican archive after Florence to find more ciphers. On their first visit to the Vatican archive they took some photos from cipher ledgers. However what they didn't appear to do is search for enciphered letters.
