There are many QR code generators available now; I’m using Google’s generator because it gives a convenient option to shorten the URL as part of the process. (A long URL creates a “busy” QR code, which is more difficult to scan than one less cluttered.)
Example of An Impossibly Long URL (from the Library of Congress)
http://memory.loc.gov/cgi-bin/ampage?collId=lprbscsm&fileName=scsm0601/lprbscsmscsm0601.db&recNum=0&itemLink=r?ammem/scsmbib:@field(DOCID+@lit(scsm000601
1. Copy the URL of the webpage.
2. Go to http://goo.gl. (You must have a Google account.)
3. Paste the long URL into the box.
4. Click Shorten URL.
5. Click Details.
6. Copy (or save) the QR code
