Original · 93 words
A local library tested a four-day schedule for six weeks. It kept the same 40 weekly opening hours, closing Wednesdays and extending Monday and Thursday evenings. Visits rose from 1,200 to 1,320 a week, although Wednesday visitors had to change plans. Staff reported fewer interruptions, but productivity was not measured. Longer evenings may help people who work during the day; this does not prove every library should open fewer days. Before making the change permanent, the team will survey residents, compare costs and repeat the trial in winter, when travel habits may differ.
First rewrite
A library conducted a four-day a week trial over six weeks. During this time the library was open for the same 40 hours as before but closed on Wednesdays and opened for longer on Monday and Thursday evenings. Staff reported fewer interruptions but productivity was not measured. Increasing hours on days when the library is already open late may help those with day jobs but the trial doesn’t provide evidence that all libraries should reduce the number of days they open. The library will be conducting a resident’s survey, comparing costs and repeating the trial in winter when travel is likely to be different.

Score breakdown
| Dimension | Weight | Score | What we found |
|---|---|---|---|
| Meaning & facts | 30% | 6/10 | Preserved schedule and productivity caveat, but omitted attendance figures and Wednesday-user inconvenience; winter wording is more certain. |
