Harvey these 3 ring binders are fascinating as in they never occurred to me but still fits what I'm looking for.
They throw out sizes like "11-7/8 x 11-1/2"." but that's the size of a single page that fits 4 (or 4 more on the back CDs). Notice they are using the terminology "insert cards" instead of all my crazy made-up terms.
Now....I have binders....if I could get on like an ebay and find the price per sheet (page) I could get a bulk deal for 25 or so. Your links are pricey because one is not getting enough for the dough and blame that on the Deluxe D Ring binder they throw in. Deluxe D ring binders are basically free at thrift stores.
Harvey, I share that peculiar trait with you. I get very curious about the mundane--enough to research it, too. And this was as mundane as a question as I ever asked, so thanks for your research.
EDIT:I don't have 600! About a 100. But good lord that mimics the classic hanging hook file folders system from the last 100 years! That kind of system is built for organization! Kill em All is good early along with Justice--a badass era for them...at the end of the day the weird Breadfan is still my favorite early record because they at least showed a rare sense of humor. Lulu is my second favorite but everyone hates that one.
