looking at grammar
Another way (however superficial) to determine the accuracy of a given resource is to acknowledge the existence of any spelling or grammatical errors.
Whenever a resource is subjected to any sort of peer review or other editing process, it is not only examined in terms of content accuracy and validity, but also in its linguistic fluency. Any errors, grammatical or otherwise, that are encountered in this review process are corrected before the resource is published. If you are able to pin down any spelling or grammatical errors, it is very likely that the source has not been reviewed, and may not necessarily be as accurate as one would hope for.
