Maria Sosnowski – Editor

Specializing in INDEXING with 20 years of experience, I can provide a great index to raise the value of your book for customers. Let's talk!

Overview

I've been a freelance indexer since 2006. My regular clients come back to me again and again because I provide a solid index on time and on budget. Specialty subjects include business, law, teaching and education, children/parenting/families, and social sciences. However, I do other subjects when I feel that I can give the book the index it deserves. Example topics include insurance, space travel, dental terminology, baseball, and wine. If I feel the topic is not a good fit for me, I will let you know so your book can have a great index.

In order for me to provide you with an accurate quote for indexing, I need to see the whole book.

Please note that I am not an editor, but am a dedicated non-fiction indexer. Because Reedsy lists indexing within the editing category rather than as a separate category, indexers have to be listed as editors too, but I specialize in indexing.

Work experience

Self-employed

Mar, 2006 — Present
I've been self-employed as a freelance indexer since 2006. My clients include authors, publishers, university presses, and book packagers. I can provide you with a solid index on time, on budget, that meets your specifications. Topics I'm most focused on include business, law, education, social sciences, parenting/family, psychology, and self-help. I have done other topics and am willing to work on any book if I feel that I can provide a quality index for that material. I'm an indexing specialist who doesn't provide editing or other related services - I just do indexing.

Clark County Law Library

Nov, 1999 — Present
I work part-time in a law library that is open to the public, providing reference services and doing all that is needed to run a small business. Providing reference service gives me many opportunities to see how people use indexes, which helps me to provide more accessible indexes in my freelance work.

I practiced law for 6 years after obtaining my JD degree. This job provides the education and background for my legal indexing.

How do you estimate how long a project will take?

For indexing, I consider many variables such as: Word count Is this a trade book written for a general audience using simple language? A scholarly book written for experts using advanced/specialized language? Are there figures, tables, notes, etc. that need to be indexed? Are there factors th...

What should I do if someone has already written a book with my idea?

Write a better book. There are many books written about the same topic, same ideas, same plots. You can't protect an idea, only the written expression of that idea. Go write your own book that is thoughtful, well-written, and thorough. A good book will find an audience.

What advice would you give to someone who wants to become a full-time writer?

Write. Write every day. Work on your craft. Join a writers group and share your writing with others, get feedback, and provide feedback on their writing.


Writing is like exercise. You have to work on it consistently and build it up over time.
