A heavy user of libraries, which a bibliographer necessarily is, has been helped by a host of individuals over many years, even decades in my case, many of the people being workers behind the scenes. I am indebted to staff members of the above institutions. As the end of the project came in sight, my calls for help, especially by email, increased; and many librarians checked a volume to see whether it contained WTW; some sent scans or photographs; some arranged for their institution to digitize copies that I needed to see; and some told me of appearances of WTW that had been unknown to me.  I have attempted to record the individuals and their institutions, and omissions from the list below are the result of human frailty, not lack of gratitude.  I hope that the list serves two purposes besides conveying thanks. One is that it demonstrates concretely that we are far, far from having everything digitized. The list, by reminding us of the demands placed on librarians by others outside their usual clientele, also shows that creating new knowledge of the past is an international project, with numerous valuable sites.
