Describe a companion workbook by stating the reading it assumes and the work it helps readers perform. Identify the relevant source edition where that affects exercises or references. Make the title, description, and introductory guidance agree about whether the workbook stands alone or depends on another book.
Identify the dependency before writing the description
Read the workbook as someone who has not seen its source book. Mark exercises that refer to concepts, examples, or passages explained only elsewhere. The word companion may suggest a relationship, but it does not tell readers exactly what they need in order to use the material.
For example, a writing workbook might ask readers to apply the five-part scene method from another volume without teaching that method. That is a meaningful dependency. Record it explicitly rather than assuming that a short introduction makes the workbook independent because it briefly names the five parts.
Distinguish added practice from repeated instruction
List what the workbook contributes beyond the source book: exercises, space for responses, worked examples, discussion prompts, or a structured practice sequence. Explain these additions in the description using the actual contents. A reader should be able to understand why the second book exists.
If substantial instruction is repeated so readers can work independently, test whether the necessary explanations are genuinely complete. Avoid using standalone as an attractive label while leaving important steps in another volume. Conversely, do not describe a self-contained workbook as requiring another purchase when the manuscript does not support that claim.

Check references against the intended edition
A workbook may refer to chapter names, page numbers, or exercises in a particular source edition. Verify those references and identify which edition the workbook was developed around. A revised source book can change the relationship even when its main title remains the same.
Prefer stable references where they serve the reader, but do not assume that a chapter title can never change. Preserve a reference map during production so updates can locate affected exercises quickly. The description should disclose an edition dependency when it materially affects the reader's ability to follow the workbook.
Explain the relationship without inventing affiliation
Review the title and contributor presentation to ensure that they accurately describe the relationship between the books and their creators. If different people are responsible, do not let the design imply an endorsement or official connection that has not been established. Resolve the relevant rights and representation questions for the actual project.
Use current KDP metadata guidance when preparing the book details. Keep the factual relationship separate from the promotional description of the workbook's benefits. Calling a book a companion explains a function; it does not, by itself, establish who authorized it or what relationship exists between its authors.

Align the cover and introductory guidance
Compare the cover wording with the description and the opening instructions. A reader who buys from the cover's promise should not encounter a new requirement only after opening the first exercise. State the dependency at a useful level of detail wherever it affects the buying decision.
The opening guidance can then explain the working sequence: read a section, attempt an exercise, consult a model, or review a response. Keep that practical explanation consistent with the metadata. If readers may use the books in several ways, distinguish the supported paths without presenting every option as equally complete.
Recheck the relationship when either book changes
When the source book or workbook is revised, compare the dependencies again. Removing a source chapter can leave a workbook prompt without its necessary background. Adding instruction to the workbook can make an earlier dependency statement inaccurate in the other direction.
Save the final positioning decision with the reference map and the manuscript versions it covers. This gives future editors a concrete basis for maintaining the relationship. The finished metadata should help readers choose the right combination of materials, with a clear understanding of what the workbook supplies and what it expects them to bring.
Frequently asked questions
Clear answers for this publishing decision.
Does the word companion explain every prerequisite?
No. Identify the actual source material or knowledge needed to use the exercises. A broad relationship label may leave readers uncertain about whether another book is required.
Should I mention a specific source edition?
Do so when differences between editions materially affect the exercises or references. Verify the relationship against the actual source and preserve a reference map for later updates.
Can a companion workbook also stand alone?
It can if it provides the instruction needed for independent use. Test that reading path directly and make the description consistent with what the manuscript actually supports.
What should the title, subtitle, description, and keywords look like before I upload?
Check the mechanical limits first, then make sure title, subtitle, categories, and description describe the same book for the same reader; a keyword is useful when it matches how that reader searches, not because it is popular.
