A little over 18 months ago in the first half of June 2018, I blogged about my prediction that the Pratt Library (Baltimore, MD) would take on passport services based on information contained in a Baltimore Sun article.
For the full blog post see http://www.danramirezlibrarian.com/2018/06/
Back then I was 95% certain that passport services would be implemented. I allotted the remaining 5% for a chance of error.
My timing gave a six to twelve month window for implementation.
How did I do?
I give myself an A minus. My prediction turned out to be true. See https://www.prattlibrary.org/passport/ for details.
I was off on my timing. I was six months short. It would have been difficult to be precise on the start date for the service, but I gave it a good attempt.
