I suggest the tool RefWorks for organizing citations for the following (and other) reasons:
- quickly create and format bibliographies in APA Style
- direct exports into RefWorks from BU Libraries Search, Google Scholar, ERIC, etc.
- your account is online; no worrying about device failure
- BU currently has an institutional subscription, and you can continue access as an alum.
However, if all you're looking for is a tool to format citations without all the storage, sharing, or advanced features, both BU Libraries Search and Google Scholar offer "cite" features on each record. These other resources may also suit your needs.
Whatever you choose, be sure to check your citations carefully for errors!
