世界观不同 何必多言。每个人的认知不同 成长环境决定一个人的眼界，少见则多怪也。

Strongly agree too many version for the same book，some even have worse translation or exactly same content like others which have been upload previous. Books selection is one of top priority tasks for the Z-Lib when upgrading to the new Version of site.

Z-Lib resouceses only can be sent to kindle by EPub format，other format can not be sent to kindle on Z-Lib official website. Anyone know why？ Thank you.
