Where it usually starts
A directory usually begins as a spreadsheet of firms exported from somewhere and published as a list.
- Areas of law are free text, so "employment law", "Employment" and "HR disputes" are three different filters.
- Offices are a single address field, so a firm with four branches appears once in the wrong town.
- Firms email the operator to correct a phone number and the change is made a fortnight later by hand.
- Nobody knows which profiles are maintained by the firm and which were scraped years ago.
