When reading a chemistry based article, book or lab manual, it must first be checked that it is reputable. This is  first determined by the expertise of the author, or authors involved in the writing of the article, book or lab manual, as well as the references the authors provide for the source written.

Most chemistry written articles and ect. are written by multiple authors. Having more than one author can make each of the claims made more reliable, because more than one person is backing it up. The authors all also have their doctoral degrees in chemistry and work at research labs in colleges across the U.S. A doctoral degree in itself show that the author knows what they are talking about, so when there are many authors with this degree, you know that the source they have written about is accurate. Doctors of professions are trained to be extremely good at what they have their degree in.

The expertise is also proven by the references that the author or authors have made, as well as how many other authors have referenced their work. In chemistry a good reputable source is one that shows where all their work has come from, whether it be other sources, or from research they did themselves. If no reference is given, there is a good chance that the information provided may not be accurate.
