Miquelrius A5 notebooks are my everyday notebooks, because the paper is interchangeable with the paper in my A5 Filo. I especially love the plastic-covered ones (the cardboard covers are too thick and stiff for my taste), designed by Agatha Ruiz de la Prada.
The only drawbacks are the expense -- US $7 or US $8 per book -- and limited availability. I used to have to go to a large chain bookstore or The Container Store to find them. Imagine my surprise when I found them at the Fed-Ex Kinkos store just a few blocks from my house!
This Kinkos has increased its office-supply and book stock and cut down on space devoted to self-service copiers and computers. I guess they've decided they make more money from retail sales. In addition to Miquelrius in A5 and A4 sizes, I also found Mead notebooks and composition books (well made, but the paper is way too thin), Cambridge notebooks (Mead's high end), Black and Red notebooks, and a rare (in the US) A4 Topps notebook.
I bought 2 each of the red and blue patterns shown here, plus a dull, professional pinstriped one for work. I wanted to buy them up to encourage the store to continue carrying them.
I still can't find Miquelrius A5s at less than $7, but I figure it's the price of a glass of wine in a nice restaurant, or 1.5 glasses of wine in a lousy restaurant. Well worth the price, since I can use each notebook for a couple of months, while the wine lasts me maybe 1/2 hour per glass.
Here are the scans of Filofax's Travellers Checklist, an English printing copyrighted in the late 1980s. 
I had planned to upload the scanned Traveller's Checklist today, but it turns out the scanned document is a PDF, which I can't upload to either Blogger or Flickr. I will have to figure out a way to convert it to JPEG. 
Today's the Vernal Equinox -- the first day of spring in the Northern Hemisphere -- according to the World and Time page in my Filofax. It's the Autumnal Equinox, first day of autumn for our antipodal friends. Although I heard from one of my Gothamite friends that New York City had snow for about an hour today. 
Here's Filofax's kindly reminder to me to turn my clock an hour forward. The USA and Canada (but not Mexico) are again observing an extended DST period - March to November. That means 8 months DST -- twice as much as Standard Time! Maybe we should call this Standard Time and the other four months Winter Darkness Time!
