Looking at this challenge I felt very lost, because while I've been back in fandom for a while now, most of my fannish web surfing is done on social media/discord and, for writing, on fandom wikis (to check on canon stuff) and Pinterest and image search engines of various types (for inspiration, especially for period stuff).
I do research, but usually it's very specific to the story that I'm writing and that leads me to different websites each time.
Then I thought that all those good resources for one thing or another will go lost at some point if I don't save them properly.
Of course, this post of course is not the right place to dump all of my links, but I've decided to find again those that came up to my mind before it's too late and link them here, for now, at least to trace them. So, have three main resources for writing (dictionary, first names, fashion) and then... a few websites that help with cartography, surveying, and planning (fictional) journeys.
Very random stuff, isn't it? But in truth you'll never know when you are going to need it...
Thanks for reading!
