The Library at the University of Cambridge has an online exhibit of Dominican books from their collection, entitled "A Pipeline From Heaven - 800 Years Of Dominican Books". As the introduction page explains, the term "pipeline from heaven" is a quote from Humbert de Romans Commentary on the Rule of St. Augustine, wherein he is describing the attitude of the friars toward their books.
There are numerous pictures of some old Dominican breviaries and missals, which may interest readers of this blog. Of particular note is the beautiful illustrations and illuminations that graced the pages of these magnificent volumes.
The exhibit is available here.
