The 2018 199th edition follows the successful format of previous editions with families listed by rank in their corresponding parts. Births, marriages and deaths of all members of the Gotha have been updated.

The Times Literary Supplement praised the Almanach de Gotha for "its punctilious itemization of titles, lineage and heraldry [aiming] for scholarship rather than sensation". Sir Stephen Runciman wrote in the Spectator"In this present age, which we are often told sees the twilight of royalty, it is comforting to be able to welcome the reappearance of the most distinguished of genealogical almanacs." The 2018 199th edition follows the successful format of previous editions with families listed by rank in their corresponding parts. Births, marriages and deaths of all members of the Gotha have been updated and it remains the only publication to list all the members ofall the imperial, royal, princely and ducal houses and the courts of the Holy Roman Empire. Even family disputes are handled by the careful noting of competing claims. This new edition also sees a full list of the households of the courts of Europe, diplomatic listings and significant updates in the chapter devoted to the Holy See, including the comprehensive listings of new appointments made by the Pontiff to the College of Cardinals and elsewhere. In addition, this edition includes the deaths of King Michael I of Romania (the late Chairman of our Société des Amis), the Princess and Landgravine of Hesse and the Duke of Coimbra, the birth of the Duke of Dalarna, and the marriages of Prince and Princess Ernst August of Hanover and the Hereditary Prince and Princess Friedrich-Ferdinand of Schleswig-Holstein-Sonderburg-Glücksburg, as well as the creations of the Marchioness of Castell'Arquato and the Countess of Barceto. This is the official and authorised publication. The most comprehensive listing of its kind, with an impeccable pedigree, the book remains an essential reference for genealogists, libraries and scholars. There is and never has been a comparable source, a book once described as "the second most important ever published".
