Over the past couple of years I have been dabbling with the Héritage collection with varying degrees of success and exasperation, but recently I had a Eureka moment – you can find the microfilm reel number in the LAC catalogue. You may still have to scroll through hundreds/thousands of pages to find what you are looking for but at least you will know that you are looking in the correct reel. N.B. There are some reels missing from Héritage and much of LAC’s collection is not available online. Note that the ‘Online’ filter applies only to documents on LAC’s own servers and should be disregarded for Héritage searches. URL syntax: http://heritage.canadiana.ca/view/oocihm.lac_reel_c5734/3?r=0&s=2 c5734 is the reel number – no hyphen. You will get a ‘Page Not Found’ error if the reel is unavailable. 3 is the page number – if you pick a number out of range you will get a ‘Page Not Found’ error. r=0 is the orientation – scale 0 to 3. s=2 is the size/definition – scale 1 to 6, 6 being the largest.
