I use Zotero Standalone (ZS). I've just finished a master's degree and I have a lot of journal articles that I want to keep, which I have in My Library in ZS - all business related. I also have a sizeable collection on my computer of old books and magazines (genealogy related). Because business and genealogy are unrelated, I want to add a second library in Zotero to categorize the genealogy collection - I don't want to mix my libraries. I use a lot of folders to categorize my business collection and I need to be able to do the same thing with the genealogy collection. How can I add a separate library in ZS for my second collection? Thanks for the help - I've just started using Zotero and really like the program!
