Yes indeed, his pdf book about 19th history of accordion and free reed instruments was subject in international symposia and conferences.
This pdf book has plenty of information and details, many footnotes. Off course, some questions remain to be solved, but this publication is a stimulus for further research.
A good thing this Spanish book was translated in English.
The bibliographic list is long.
The conference paper, edited by Claudio Jacomucci, is more oriented to the future and accordion education, pedagogy, from teacher's perspectives.
Let's hope these publications will attract large readers numbers from all over the world, that's why they are written in English.
It must have been a lot of work to collect all the information and write the texts
I'm also very interested in the 6 books Rob Howard wrote, A to Z accordion, Vintage accordions, etc. But these publications are very hard to find on the continent in Europe. They were published by the author and I can't find them in our music shops.
