Many of the items in HathiTrust Digital Library are protected under copyright law, meaning that full-text viewing is not possible without the express permission of the copyright holder. Those items in the public domain can be viewed in their entirety (e.g. such as U.S. works published before 1929), as well as U.S. government documents, and items where the copyright holder gave permission to HathiTrust. Details about copyright can be found at https://www.hathitrust.org/help_copyright.
Additionally (from the HathiTrust web site): "Works published outside the U.S. prior to 1928 are in the public domain; however, due to the variations in copyright law in countries outside the U.S., it is estimated that 1898 is the earliest date foreign works may still be under copyright. Therefore, users accessing the volume from U.S. IP addresses will have access to the works published outside the U.S. from 1898 through 1928; however, users with non-U.S. IP addresses will not."
Not everything that has a record in HathiTrust Digital Library is available in its full-text form (indicated as "Full View"). Some books and journals have an "viewability" status of "Limited (search-only)."
Those works that are still under copyright display a "Limited (search-only)" status. You can still search within those works for your key terms, to better understand if the work has the content and context you seek. You can then place an interlibrary loan request to borrow a print version (full text) of that work for your research purposes.
