The .tcr filename extension is a compressed text file format for eBooks and text associated with eBook reader software developed by Psion, a London based techonology company. The format has its beginnings in the early 90's and was designed for use on the PDAs released by the company, particularly the Series 3 handheld PDA. Though the format is proprietary and was intended for exclusive use on Psion devices, today, a few eBook reader applications can open files encoded in this format. As PDAs eventually lost there popularity, the format was discontinued when Psion eventually pulled out of the PDA market.
The .lit filename extension, short for literature, is a proprietary filename extension of the eBook file format LIT developed by Microsoft. The format was initially released in 2000 and at the time was only compatible with Microsoft Reader. Though DRM support was one of the strong selling points of the LIT format, wide spread DRM circumvention discounted its utility in favor for competing open formats. This among other reasons caused Microsoft to officially discontinue support for the format by 2011 and cease further sales of eBooks based on the format completely by 2012.

The TCR format boasted of better compression of files saved in this format in comparison to its closest rival at the time, PalmDoc. The format is an adaptation of the ZVR text file viewer format developed for Psion, but incorporates the compression algorithms used in the TCReader program which was faster than that used on the ZVR format. The company claimed a 50% on average saving in memory storage after compression to TCR.
The LIT format was extended from Microsoft's compiled HTML help format. The format includes support for digital rights management to enforce copyright material. This is however an optional feature.
