Archived messages

How do I access archived message logs? I had a conversation with some of my bandmates over facebook and in that conversation I sent over some lyrics and sheet music. The notebook I kept some of my material in was recently destroyed and my other bandmates have the rest of the material but I lost the music for one song. However, I found it in the facebook messages while I was on my phone. Worried it would be lost, I clicked "Archive". To my dismay, it disappeared off of my phone and I couldn't find it. Now since I clicked archive I presume it was, well put into archives. Question is, how do i access said archives?
