01
Set the decision criteria
Choose the factors that matter today: topic, stated prerequisites, edition, format, examples, or reference value. Avoid treating length as an automatic measure of quality or difficulty.
02
Separate facts from impressions
Record catalogue facts in one column and your questions in another. If a sample suggests an accessible style, label that as your impression of the sample rather than a verified judgement of the whole book.
03
Compare equivalent evidence
Look at descriptions or samples on both sides. A detailed impression of one book and a title-only guess about another do not form a balanced comparison.
04
Choose the next useful fit
Explain which book better matches your present goal and what would make the other a better choice later. You can make a clear decision without declaring a universal winner.
