I maintain a list of books in my library in LibraryThing, and have actively contributed to that website.
- Is it possible to import one’s library from LibraryThing as a BookBrainz “collection”
- Is it possible to import books from LibraryThing that I’ve contributed?
(The LibraryThing contributor licence makes it clear LT doesn’t assert copyright over contributed information:
We do NOT assert copyright over the things you post to LibraryThing. The phrase “non-exclusive” above means you can post your content elsewhere.)
