In preparation for a recent outreach visit, I did some searching on the library's resources in the history of Islamic medicine.
Primary sources on this topic are rather thin on the ground in our rare book collections, which tend to have a traditionally Western focus. The Sydenham Collection includes a translation of A treatise on the small-pox and measles, by Abū Bakr Muḥammad ibn Zakarīyā Rāzī, (Rhazes).
The History of Medicine Collection includes The book of ten treatises on the eye by Ḥunayn ibn Isḥāq al-ʻIbādī (Johannitius), in edited Arabic text and English translation.
I was pleased to see that the library's main collection includes several more translations of primary sources from the Islamic Golden Age, including writings by Avicenna and al-Kindī, and Arabic versions of Galen and Hippocrates. The library also holds secondary resources on the history of Islamic medicine.
