TrEE is a free, public, curated library of Transportation Energy and Emissions literature. The primary focus is scholarly works such as journal articles, books, conference papers/presentations, research reports, statues, and theses/dissertations. But the library also tracks, for example, magazine articles, web pages, and patents.

This online version of the library shows all the items, but has very limited features. To enjoy the full benefits, please register and install Zotero 5.0 and Zotero Connector. You can do this on multiple computers and often Zotero can be installed without admin rights. Then, connect your local Zotero software to your Zotero login (via Edit > Preferences > Sync) and then click to join this group.

If you wish to *contribute* to the bibliography in TrEE, you also need to join the sub-group, TrEE_branch: https://www.zotero.org/groups/510068
