British Library Hebrew manuscripts site.
Research into pre17th century Jewish calligraphy and illumination is difficult to find. Here’s some great information on this topic. Thank you MARYA KARGASHINA
A useful looking resource:
The British Library has set up a new page focusing on Hebrew manuscripts, many medieval. The digital collection includes Haggadahs, Torahs, Pentateuchs, and various treatises. Additionally, the site has articles explaining various aspects of these manuscripts.
