Duplicates, material of little evidential or information value, and strictly personal documents have been returned to Secretary Baker. A large volume of newspaper clippings from major American newspapers have also been returned.

The February 2011 accession originally included four additional series, which were subsequently separated.

A series of board membership records spanned Baker's pre- and post-Washington career (additionally, some files from his work on the boards of regional organizations during the 1960's and '70s were interspersed throughout his personal financial records). Board participation during his post-Washington career includes work with St. Luke's hospital, Rice University, the Howard Hughes Medical Institute, the University of Bremen, Electronic Data Systems, Radiant Energy Corporation, and King Ranch. These records encompassed twenty linear feet, were non-unique, and of extremely limited research value.

A series called soft costs documented accounting within Baker Botts of how to expense Baker's political work using Baker Botts resources was also removed from the collection. The series of two boxes consisted of spreadsheets of phone logs and billing codes, and no material regarding the substance of Baker's political work.

A series of campaign contributions from Baker's 1978 Attorney General campaign included two boxes of index cards of campaign contributors' contact information.

Finally, the "Income Tax Records" series is the only surviving part of what was once a series of personal financial records, spanning the 1960s through the beginning of the Reagan administration, which included cancelled checks, financial statements from investments, receipts, tax returns, trust statements, documentation from family legal issues and statements from charitable organizations. Because these records included personally identifiable information and were of limited research value, the vast majority were separated from the collection, although Baker's tax returns were retained.
