Latin abbreviations in manuscripts

Greetings everyone,
I am new to this forum and am very excited to find it exists. My situation is that I possess rusty schoolboy Latin and have been set the task to translate some Latin texts (renaissance manuscripts -the letters of Marsilio Ficino) with a group of others whose latin is not much better than mine. the manuscripts contain copious abbreviations which make the task even more daunting, I have a list of common abbreviations but would like a complete list -can someone provide such a list or inform of a source for it?
Many thanks

Well, there is always Cappelli. See for example the online version here:

Would it be possible to post any images here? I’ve been studying paleography a little this semester, and combined with my natural interest in humanist Latin, it could be fun.
