As an author, I’ve come to really value Evernote.
For instance, I’ve had to look up historical information, geographical information, temperature, weather, customs, language, names, name meanings, historical personality, cars, houses, etc.
Evernote gives you a place to store all that.
You can bookmark things like name generators. You can clip locations, inventions, all kinds of research. Think of Evernote being a filing cabinet. And every now and then you have to re-organize it to make more sense.
Try Evernote for a year, free. If after that you’re finding you’re routinely running out of space for it, consider upgrading to plus.
You’ll need one admin day a month to go into Evernote, and update tags and make sure you clipped articles to the right notebooks.
