After watching Thomas MacEntee's talk on the Internet Archive during THE Genealogy Show, I returned to this data-rich resource with fresh ideas of what was available and how to search.
Not only is the Internet Archive entirely free, it has some scanned resources from places that I would otherwise have to visit and research in person. See for yourself at https://archive.org.
Searching for John D. Slatter
Because Canadian collections are well represented on the Internet Archive, I began with a new search for Capt. John Daniel Slatter (1864-1954), my husband's great uncle. At the turn of the 20th century, Capt. Slatter was renowned as the leader of the internationally-known Kiltie Band, the 48th Highlanders of Toronto.
He was listed as Bandmaster, 48th Highlanders, and a teacher of cornet, French horn, slide trombone, euphonium, and tuba. Our family never knew this ancestor played tuba, and we never knew he was on the faculty of this institution.
Also I found calendars for the University of Toronto, for the period 1913-1917. John D. Slatter was listed in the university materials as being on the faculty for the Conservatory of Music in those years. The Conservatory had an affiliation with the university, listing faculty for both institutions. It's a small thing, but we didn't know about it.
Next, I'll plug in more Slatter names, because Capt. Slatter had two bandmaster brothers also in Canada. With luck, one or both will be in the Internet Archive.
UPDATE: I found new results for Captain Albert Slatter and more results for Capt. John D. Slatter! Nearly all out of copyright (check rights document by document) and available to post here and on my family trees. Below, Capt. John Slatter at center of front row, leading the U of Toronto band in 1937.
