Even if you cannot get to the library, there are still large collections of full-text government publications you can access. Listed here are freely available digital collections. They include historical titles, originally in print, that have since been digitized and are available as PDFs or web pages.
govinfo.gov is a very good starting place. It is the central repository for primary documents that reflect the activity of the US government. This collection is already large with more being added everyday, and includes both historical titles and new digital documents. Among the major series you can find:
Archives.gov — is the homepage of the National Archives (NARA).
