relatives of the ainu language?

[ex_heracles30]

This is homework help in a sense, but I'm not asking for anyone to answer questions or do my work for me; I just need a few pointers in terms of where to start looking for sources. If this isn't allowed, let me know and I'll take it down.

( a bit of backstory on my research paper. )

Basically, I'm looking for some good sources that discuss the Ainu language itself. My campus library has been surprisingly unhelpful; I've already found some good books and articles with regards to the biological aspect of my paper that I have to request from other campus libraries. I'm not asking for people to help do the research, I'm just hoping someone will know where I can get started doing it myself. Any books, articles, etc. would be extremely helpful.

Again, if this isn't allowed, let me know. Thanks in advance.
