Hey all!
I finally began importing my knitting and crochet patterns into a new Calibre library. It's tedious, since I can't just "download metadata" but it takes away the ridiculous need to "organize" my patterns on my hard drive.
I thought I'd share a screen snip with you showing my custom columns for this library. I've only finished importing "shawls" (now, if I can stop finding MORE to download!

) and the process is sooooooo tedious. I suspect I'll end up doing "bulk" adds by category to get the category and the craft marked correctly -- and go back later to add yarn weight and yardage/meterage.
If my programming experience wasn't so antiquated (!), I might try to use the Ravelry API to make a plugin for Calibre. If someone out there IS doing this, please point me to them -- I'll be glad to be a guinea pig!
To appropriate a commercial phrase, "What's in
your Calibre?"
