Many resources can be found on our parent organsisation http://www.ki-society.org.uk.
This includes a number of articles written by Doshu Yoshigasaki over the years.
There are some videos on this site under the video link The All of Aikido set give a comprehensive link of most of the techniques.
The end of the first video has Sensei demonstrating a curtailed Misogi session. The beginning of the fourth video also has Sensei showing some Teateho. Both are worth a look if you haven’t seen this in detail before.
Heike Howein and Marcus Schien have produced a set of videos going through the syllabus a few years ago. Here is the link https://vimeo.com/user28905555
Michael Holm has also gone through the syllabus. Here is a link to his media page. We have the syllabus at the bottom of the page. http://www.toitsu.dk/ki/media.html
Michael Winter has also his video on Youtube of all the Tszukiwaza. If you google ‘michael winter aikido‘ you will find his videos.
Of course, all these videos should really only be used as a guide. Things change over the years. Also the instructor might be emphasising a particular point in their practise for their students which might not be relevant to you.
Doshu Yoshigasaki Sensei has also written a couple of books if you prefer a written reference.All of Aikido that documents most of the techniques we have in our syllabus. Sensei also wrote a book about meditation called Inner Voyage of a Stranger
Sensei last book, which he completed shortly before he passed away, is about Aikido in Real Life. Here is a link to get that book
There are also some older books by Tohei Sensei which are a good resource. Here are a list of his books from Amazon
Of course, Aikido cannot be learnt exclusively from a book or video. Ideally you should look for a trained instructor who can help learn the art.
