That would be correct that non-Masons are not permitted to exemine the minutes.
Art. 338. Inspection of Minutes: By Whom. The minutes of the Lodge are the private records of the Lodge and no copy of same or any part thereof, shall be made or used for other than Masonic purposes. They shall be securely kept and preserved by the Secretary, and shall be open for inspection at reasonable times by the officers and other members of the Lodge, or by such other Masons as have an appropriate reason therefor, but not under any circumstances by those who are not Masons.
But the minutes for the purpose you described can be taken care of in this manner.
Art. 338a. Summary of Minutes Permitted. For purposes of providing accurate historical and genealogical information con-cerning the Lodge and its members, a summary of the minutes and records of the Lodge may be prepared and published in a form and manner that would not bring discredit on the Masonic Fraternity and the Lodge or any of its members, past or present. If the sum-mary is sponsored by the Lodge, it must be presented to, and approved by, the members of the Lodge prior to publication.
Sources of Lodge information include, but are not limited to, Lodge minutes, Annual Returns to Grand Lodge, Masonic records of individual Masons, membership files, general Lodge documents, records and files, and Lodge correspondence. Additional sources of information include Grand Lodge Proceedings, Minutes of the Grand Lodge, and Lodge records in the Archives of the Grand Lodge.
In preparation of the summary, the Lodge is to strictly conform to the applicable provisions of Art. 506; Art. 405a; Art. 421; Art. 427; Art. 594; Art. 602; and Art. 605. Further, the summary cannot contain any libelous matter which would include the following: (a) blackening the memory of the dead; (b) injuring a living person’s reputation and exposing the person to public hatred, contempt, ridicule or financial injury; (c) impeaching any person’s honesty, integrity, virtue or reputation; or (d) publishing a person’s natural defects so as to expose that person to public hatred, ridicule, or financial injury. The summary may include, but is not limited to, the following listings:
1. Members of the Lodge;
2. Past Masters and Affiliated Past Masters;
3. Officers of the Lodge;
4. Changes in Membership for any reported year including names of Members:
In addition, the summary may include awards presented to Lodge Members, obituaries of deceased Members, recognition of Members for past historic, patriotic or community services pro-vided, or awards given, as reflected in the minutes of the Lodge.
