**Can I find All FRA Documents in the Library?**
Some "documents" may not appear here for the following reasons:

Document resides on an external site for the record of source, links to the document are provided in context but not in the library as FRA does not maintain this record. This document lives on another website.
	Document has not yet been assigned keywords.
	Document is historical and has been removed from library to avoid confusion with current publications.
	Document is public affairs & policy related, such as press releases, speeches, testimony, or fact sheet. These press-related documents can now be found in the FRA Newsroom.
	Document is related to rules and notices. This information can now be found on the Rulemakings search and the Notices search, respectively.Refine Your Search
            **To search an exact document title or key phrase, place quotations around the text. Example: "U.S. Government Grade Crossing Research & Stakeholder Engagement" Entering keywords without quotations will search the eLibrary for all occurrences of the keywords.**
