The article identifies the wrong congressional body. Contemporary congressional records show that the contempt matter involved the House Committee on Armed Services’ Special Subcommittee on Intelligence, not the Senate Watergate committee.

A House hearing volume is titled Inquiry Into the Alleged Involvement of the Central Intelligence Agency in the Watergate and Ellsberg Matters: Hearings Before the Special Subcommittee on Intelligence of the Committee on Armed Services, House of Representatives. Congress.gov’s summary of H.Res. 536 likewise says the House acted on Liddy’s refusal to testify before “a duly authorized subcommittee” of the House Armed Services Committee.

So the sentence is inaccurate because it says Liddy was convicted for refusing to testify to the Senate committee investigating Watergate, when the refusal at issue was before a House Armed Services subcommittee.

The ISBN listed for When I Was a Kid, This Was a Free Country does not match reliable bibliographic sources.

Publishers Weekly’s review of the book gives the 2002 Regnery edition as ISBN 978-0-89526-175-5. Library and bookselling metadata in search results also identify the 2002 Regnery hardcover as ISBN 9780895261755 / 0895261758.

By contrast, the article lists 978-0-312-05127-3, which belongs to a different Liddy title and is not the correct ISBN for this 2002 Regnery book.

The listed ISBN does not match authoritative bibliographic data for Fight Back: Tackling Terrorism, Liddy Style.

Macmillan’s page for the book gives the St. Martin’s Griffin edition as ISBN 9780312364380. Search-result metadata for the 2006 St. Martin’s Press hardcover gives ISBN 9780312199456 / 0312199457. Either way, the article’s ISBN 978-0-312-05127-3 is incorrect for this title.

That ISBN is therefore a bad bibliographic identifier for Fight Back as listed here.
