Bankruptcies continue to pile up in the retail industry.

More than 300 retailers have filed for bankruptcy so far this year, according to data from BankruptcyData.com. That's up 31% from the same time last year. Most of those filings were for small companies -- the proverbial Mom & Pop store with a single location. But there are also plenty of household names on the list.

Most of these stores are suffering from the same thing: A shift away from traditional storefronts to online shopping.

Not all of these chains will eventually go out of business. Most of them fled for Chapter 11, which allows a company to keep operating while it restructures its debt. But the sector is already on course for a record number of store closings this year.

Here's a list of some of the more prominent retail bankruptcies to date.

Gymboree: The children's clothing retailer filed for bankruptcy on June 11, saying it may close 375 of its 1,300 stores under the Gymboree, Crazy 8 and Janie and Jack brands.
