What documents are legal to upload?

I assume that you are talking about legality due to copyright here.

The issue is quite complicated (i have tried answering elsewhere). I can add here that if you are uploading a document in order to source your tree, you could argue that you are doing that for educational reasons, and thus it would fall under FAIR USE clause of the US copyright laws. Fair use is an interesting concept, it allows you to have a non-transferrable right to publish a portion of the copyrighted work that is necessary for educational (and some other) reasons. But when doing that you need to make sure that you follow some guidelines.

Now, i am definitely not a lawyer, but my understanding is that you need to upload the documents that are actually relevant and necessary (i think that it's understood, but still need to be said), there is also a requirement that another document couldn't be used (and if you could source the original, i think you would, so that's ok, and finally your use of the document shouldn't hinder the commercial use of it by the copyright owner.

I think that in general when you upload the document you clearly say "i got it from this site" so you are not trying to drive the traffic from there to somewhere else (in fact the opposite can be said to be true). But it is difficult to make "one case fits all" rule.

Coming back to Long Future Genealogy, you should definitely upload. Because maybe today these documents are under fair use, but later they will become public domain, and it would be a shame if they were to be lost as nobody archives them. Just keep track of where you found them, etc.

FamilySearch.org documents are definitely upload able, they are a non commercial free site; you may need a free membership in order to view optimally.

They also have built in citations, so what I do (optimally) is three fold:

1. create a custom event first on the timeline tab if it's not one of the ones built in to Geni (birth, baptism, marriage, death, burial). Most frequently I add immigration & residence as "events."

-- copy & paste in the text transcription in the event "description" field, including source citation. This is particularly useful for census reports.

2. upload document, tag to the profiles mentioned, tag to the event as document, & source / cite facts in the Geni "add source" module.

3. use their citation as a footprint in the profile "about.". That way anyone can easily click and inspect the origination for themselves, and I have a handy shortcut on the profile front page, with detail accessible through timeline, documents, & sources.

Note: if you're printing out the profile you may want that detail "on" the overview. If so, I use the Wikitext line break to "section off" facts from biography from citations to create a narrative flow (citations / footnotes at the bottom; easily visible in tree view vital stats & family relationships at the top.

Erica Howton thanks, I have not used timeline events before, can you please show me a profile like this please?

http://www.geni.com/profile/6000000013975154534/events/600000003365...

Personally i have started doing similarly, but today i try to always include the name of the person in the event title (to make it similar to automatically generated event names).

Example: Lev Nikolaevich Zinkovsky

Also, a note about work and education. Make sure to first put the information into Work and Education tabs of the profile, and only then go and begin updating the information on the timeline. There currently is no way to merge two events that are the same, you'll end up with duplicates.

So I have used Immigration should I have it as "other" ?

I am also using added tags, like ship name, and departed from.
