Turning a Printed Buyers Guide Into a Searchable Map: A Sheet of What to Settle First, From Six Sources on Other Directories

A publications or membership manager holds a printed buyers guide, or a member directory that exists as a list, and is asked to publish it as a searchable map. The decision has several parts: whether a map should lead, what sits beside it, who can use it, how the entries stay right and what a pin reveals about the people listed. We read six documents that bear on those parts, and none of them describes an association’s buyers guide, directory or supplier map. None of them tested whether a map brings an association more use or revenue; our article on online buyer’s guides argues that question from other evidence.

A sheet to settle before a list becomes a map

Fill in one line for each part before anyone chooses a mapping product. The moves are our reading of the sources below, and we have not tested them with an association.

Part	Question to settle	First move
What opens the guide	What do visitors pick first: a place, a category or a company name?	Keep categories and a search box on the first screen beside the map, and watch a few visitors use it.
What sits beside the map	Does every entry also exist as plain text?	Publish the same entries as a list or table next to the map.
Who can use it	Can someone find, filter and open an entry with a keyboard alone?	Test with a keyboard first, then ask people who use assistive technology.
How entries stay right	Who checks each entry, and how often?	Contact a sample of listed companies every cycle instead of waiting for them to report changes.
What a pin reveals	Is any entry a home address?	Leave home addresses off the map, or ask the person first.
What listed people were told	Did each person agree to be listed, and can they correct or remove an entry?	Write the notice and the removal route before launch, and ask a lawyer what applies where you operate.

What one small pilot of phone searches shows

A 2014 conference poster, by three authors at the University of Applied Sciences Potsdam, reports a pilot in which more than 25 people were tested and 20 valid datasets remained. Participants used a web app on a phone, fed by a commercial place-data service, to find a fast-food restaurant nearby and then a café in a specific area further away. Every task opened on a page with a search box, a map and a list of categories. The authors expected the map to lead for nearby searches, but the first step was a category in 65 percent of cases, and for the farther task it was the search box. They conclude that in their test the map did not work as the first screen, and they say the sample was small.

That is one pilot, about restaurants and cafés, with no supplier or association in it. It does not say a map loses to a list for finding a supplier. It is a reason to keep categories and search on the first screen and to watch real visitors before deciding.

What the state accessibility guide asks of a map

A 47-page Minnesota state guide, published in October 2024, says a map’s purpose and content determine whether it should be interactive at all. Its example pairs a map of state parks with a list of them, and it describes a public-health data portal that offers a visual and a table. It also asks that navigation work without a mouse, that pinch zoom have a one-finger alternative, that a legend be included or placed next to the map, that colors be explained in text alternatives and a legend, and that the page share its accessibility limits with a contact for another format. Its conclusion says the best accessibility software covers about 25 percent of the guidelines it references and that testing with people with disabilities comes last.

This is state government guidance with state examples. It reports no test of its own advice, and nothing in it shows that any product, or any supplier map, meets it.

Listings drift: an audit of health-plan directories

An audit report from the Centers for Medicare & Medicaid Services, a US federal agency, covers the online directories of four kinds of physician run by Medicare Advantage plans. Between November 2017 and July 2018 reviewers phoned provider offices to check 5,602 providers at 10,504 listed locations, and 48.74 percent of the locations had at least one inaccuracy. Plan by plan, the share ran from 4.63 to 93.02 percent. Providers should not have been listed at 33.14 percent of locations, and the review counted 690 wrong or disconnected phone numbers and 364 incorrect addresses. The agency saw a general lack of internal auditing among many plans and said a plan that relies only on providers to report changes will not have an accurate directory.

A physician directory is not a buyers guide, and the report measured accuracy, not how often anyone used a directory. It is the only source here that checked listings by contacting the listed party, which is the move the fourth row of the sheet borrows.

A review article by a University of New Mexico geographer says that publishing a map of individuals’ locations can breach confidentiality because a published point can be turned back into a street address. It adds that zooming in gives a very exact location, that a displacement of 100 meters protects little in a sparse area, and that no standard exists for publishing individual locations. It concerns health research data, so we use it by analogy, as a reason to treat any home-based listing as an address and not as a verdict on business listings.

Two regulators speak about directories in their own countries. A Canadian federal privacy regulator’s case summary, dated 28 March 2019, concerns a commercial publisher that took a man’s contact details from an association’s web pages into a print directory and a linked database. The page had only invited members and the public to contact him about general inquiries. The regulator found it was his personal information, that consent was required, and that the directory had listed him wrongly as an official of a provincial association. The publisher removed his details when told. A UK regulator’s guidance page, page read October 2026 and carrying a banner that it is under review, requires telephone, fax and email directories to tell people and offer a chance to opt out, and to correct or remove details on request. It also says that in the regulator’s view trade directories and club membership contact lists are outside that rule.

Both are foreign guidance, and neither covers an association’s directory in the United States.

Questions this evidence leaves open

The six documents cannot say whether a map beats a list for finding a supplier, whether a map earns more for an association, how often association addresses are wrong, or what a US association must tell the people it lists. The sheet turns that gap into six questions with a person to answer each. Write the name of that person beside each line before the first listing goes on a map.
