Inside Self-Storage (ISS) is now collecting data for its 2013 Top-Operators List, which identifies 100 of the self-storage industry's leading operators based on total net-rentable square footage. The list includes facility and brand owners, independents and property-management companies. The data also features number of locations and units, expansion plans and contact information.

To participate, companies that have been published in a past list can log in to update their existing information by visiting http://topoperators.insideselfstorage.com/BGWebForm_login.asp?gid=12. Operators who are new to the process can create a listing through the same Web page. Submissions must be complete by July 31.

The ISS Top-Operators list will be featured in the October issue of ISS magazine and published online on Sept. 13.

For more than 20 years, ISS has provided informational resources and services to the self-storage industry including a monthly magazine, annual conferences and tradeshows, and an extensive website. ISS is also the owner of the Self-Storage Training Institute, an online education portal for managers and owners; Self-Storage Talk, the industrys largest online community; and the ISS Store, a website for on-demand education and insight.
