If you haven’t yet seen it, please take a look at the Reference Shelf page of this blog. I’ve been working, quite sporadically, to populate the page with links to digital versions of reference books useful to rare book and special collections librarians. I’ve also done some listing of the contents of each volume to make it somewhat easier to find citations that bring you to those works.

My excitement of the title of this post is I now have links to all volumes of Sabin (thank you, Internet Archive!). When I had first been looking for them last year, I found all but volume 21. That one is also online now, and either it was an addition since I last looked, or had somehow been missed. It could well have been the latter. I hope you find it useful.
