A user is seeking a general chemistry book in PDF format but is struggling to find one online. They have checked the Chemistry Websites thread and found it unhelpful. Suggestions include exploring MIT's Open Course Ware for chemistry courses and the Shodor website for online chemistry resources. However, there is skepticism about finding a complete chemistry textbook online due to the extensive content it would require, including diagrams and data. One user mentions having "The Golden Book of Chemistry Experiments," which is more of a practical guide than a textbook, but warns that some experiments are outdated and potentially dangerous. Overall, the discussion highlights the difficulty of locating comprehensive chemistry textbooks in PDF format.
