If you are interested in going deeper, may I recommend "Parsing Techniques" by Dick Grune et al [1]. I have read this book over five times and still find gems hidden that I must have failed to grasp in a prior reading.
The author provides the PDF of the first edition on his website [2]. Read the last paragraph of page 60 of the book (page 50 of the PDF). I read this again whenever coming in doubt.
A great thing about the book is also its annotated bibliography. The author cites hundreds of papers for extended reading, but has also written a paragraph on each cited paper explaining the context around it, how it fits with the rest of the subject, and a quick summary of what were the key contributions and findings.
