Field notes

The described process keeps an acquisition record, including why a paper could not be obtained, so a thin evidence base is not presented as a clean absence of findings. Claimstone says it stops when the share of found material it obtained falls below a threshold set in advance. Its homepage also presents the example claim checks as illustrative, not as results from a real paper.
