Maria Sosnowski – Editor

Specializing in INDEXING for 20+ years, I can provide a great index to raise the value of your book. 100% human, no AI. Let's talk!

Overview

I've been a freelance indexer since 2006. My regular clients return 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, health issues, biographies, and home builder guides. 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 price quote please send 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 — Jun, 2026 (over 26 years)
I worked 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 gave 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.

Do editors ever experience genre fatigue?

I write indexes, and I have several topics I specialize in. Doing many projects in a few subject areas helps improve my content knowledge and is comfortable. However, I love when I get books outside those areas (as long as I feel I can do a good job with the subject) because they are a change o...

How can authors protect their rights when publishing, especially in the age of AI?

Make sure you hire someone who does not use AI. I'm an indexer. All of the indexes I write are 100% created by me, and I never use AI. When you are contracting with someone, make sure to clarify that they are not allowed to upload any part of your work to any AI platforms. Learn about copyright...
