Frequently Asked Questions (FAQs)

Welcome to the question and answer section of our main website, with plenty of links to send you in the right direction. Over time, we will be adding more questions and answers to this resource page, as well as to the related pages.

A: Please click here to review Industrial Press’s author guidelines from our Publisher Judy Bass.

Q: How many websites does Industrial Press have and what is the difference between the two?

A: We have two separate websites:

  1. Our main retail and information site:
  2. Our eBookStore site:

Our main retail and information website provides information about and a place where you can order our print and other physical products; it also serves as well as a source of information on the history of the company, the Machinery’s Handbook product family and numerous other titles, our acclaimed authors, press releases, articles, useful industry resources, and contacting our main offices and customer service department.

For information on ordering, installing, and using Industrial Press eBooks, including a demo video of our provided reader application, information on setting up your eBookStore account, the difference between a single-user and multi-user eBook subscription, and more, please click here for an informative page on this main website.

Our eBookStore website  is the site to go to if you want to purchase almost any available Industrial Press book in accessible digital format. The eBookStore site also includes detailed product pages and information on how to access and use our eBooks, online and offline, on various devices.

Note that these websites include many crosslinks, but customer accounts created at these two URLs are entirely separate. So if even if you have an account on one of these two websites, you still will have to create a separate account on the other website to order products there. Of course, no account is needed to browse and learn about Industrial Press and its products.

Finally, if you don’t know where to go, check out the “Resources” section of this main website.

Q: Can I return an Industrial Press book or eBook?

Q: I’m trying to figure out what to buy. What is the difference between the various Machinery’s Handbook family products?

A: The Machinery’s Handbook, 32nd Edition,  whether the Toolbox (a handy, smaller package), Large Print (a full-size, larger and heavier version, with print the size of standard reference books), or Digital Edition (usable online or offline on various devices and also available in an Upgrade version), contains all the vast, updated, and expanded information that makes the MH so valuable in one package. So we recommend these comprehensive, core products first and foremost. Before you buy, however, also consider our value-added combination packages and companion volumes. 

The Machinery’s Handbook Guide to Using the 32nd Edition is a great companion volume, as it touches on many of the MH31’s primary subjects. This useful guide includes both page references to the main book and numerous, unique examples and review questions. (Note: If you buy the Digital Edition, this valuable companion text is combined with the Handbook and hundreds more pages of extra material.)  

Finally, the Pocket Companion was born as a shortened, extracted compendium of some essential material in various MH editions—though it does have some added material unique to this companion book. We have updated the book so much, including the latest material from the MH32, that it is has been published as the Machinery’s Handbook Pocket Companion to the 32nd Edition. This is the kind of book you would want to have on hand if you need access to just key data. Though, we think it is most useful if you can go back and investigate more on the subject later, in the Handbook itself.

Q: What if I want to send in a question about content or regarding a possible error/suggested correction in an Industrial Press title?
