It is a reference section, not a showcase
A newsroom page is used under time pressure by someone checking a fact. Designing it as a display of achievements makes it slower to use and therefore less used. The test is whether a stranger can find the date of a specific announcement in under a minute.
Releases in date order
Reverse chronological, with the date visible next to every item in the list rather than only inside it. Older items stay at their original address permanently: a reporter following a link from an older article to a page that no longer exists will conclude the item was withdrawn, which is rarely what was intended.
Machine-readable dates
Dates written in an unambiguous format, and marked up so that software can read them, prevent the single most common error in later citation — the transposed day and month. This costs nothing at the time and is impossible to repair afterwards.
Background material
A short factual description of what the organisation is and does, kept current, saves every reporter writing about it for the first time from guessing. Alongside it: definitions of any terminology specific to the field, and the published documents that any figure in a release was drawn from.
Images and their terms
Images are useful only if the terms of use are stated plainly next to them, with the required credit line written out. Files should be available at a size a print page can use, and each one should say what it shows and when it was taken. An image with no stated terms is treated as unusable by anyone careful.
What does not belong
Sign-up walls, forms that must be completed before a document can be read, and material that exists only inside a proprietary viewer all have the same effect: the reporter uses a different source, usually a less accurate one.
