Admission is by patrimony, by servitude, by redemption, or by presentation, depending on the company and the candidate. Each route produces a different entry in the books, with the candidate's name, the route, the date, the sponsors where required, and any associated payment. The books survive in the company's archive and, in many cases, in microfilm and digital form at the relevant research libraries.

Modern publication has accelerated the visibility. Many of the livery companies publish their members' lists in their handbooks, on their websites in part, and in the magazines they produce for their membership. The historic records of the older companies have been digitised by the family-history industry, and the search interfaces now return livery company entries against personal-name queries with reasonable accuracy.

The honorary structures within the companies, the Master, the Wardens, the Court of Assistants, are themselves a matter of annual record. A liveryman who progresses through these offices generates an additional entry against their name for each appointment. The Master's year is, in the historic companies, an occasion of substantial public ceremony, recorded in the City press and the relevant trade publications.

The work in this category is rarely about anonymity, which the companies' purpose does not contemplate. It is about understanding what the existing record already discloses, how it is now circulating in the digital extensions of the family-history industry, and what considered handling of any future office or activity within the company would mean for the assembled picture.
