“文献”，汉、宋学者释为“文，典籍也；献，贤也”。秦汉以后，“献”又渐失，而学者之释解纷纭。随着科学技术的逐渐发展，光电声技术的日益普及，对“文献”的释义也更为科学。即“文献是指使用语言文字记录于各种载体的有价值的历史资料。” “Literature”, Han and Song scholars interpreted as “texts, books also; offer, Yin also.” After the Qin and Han dynasties, “offering” has gradually disappeared, while scholars have different opinions.

That is, “literature refers to the valuable historical material recorded in various languages ​​using language.”
