Contemporary artists and designers are finding the wood engraving one of the most highly desirable sources of illustration for many design purposes. Simple and bold or capable of the most exquisite effects of tonal gradation, this elegant black-and-white artwork sustains no loss in reproduction and is a perfect complement to typography. 
1,419 clear wood engravings present, in natural, lifelike poses, over 1,000 species of animals. Included are many different versions of the familiar animals most wanted and used by commercial artists and craftsmen. Arranged according to the following seven categories, the illustrations portray mammals, birds, reptiles, amphibians, fish, insects, and other invertebrates. 
Selected for their visual impact and usability by artist-collagist Jim Harter, these illustrations form one of the most extensive, royalty-free pictorial sourcebooks of animals ever assembled for the specific use of illustrators, graphic designers, craftspeople, decoupeurs, and collagists. Captions give modern common-name identifications, and a thorough index provides immediate access to individual animal pictures. Because of the accuracy and detail of most of the renderings, naturalists will also enjoy browsing through this volume and using it for illustrative purposes.

【Science：科学家利用纳米孔DNA测序技术成功扫描单个蛋白】在一项新的研究中，利用纳米孔DNA测序技术，来自荷兰代尔夫特理工大学和美国伊利诺伊大学的研究人员成功扫描了单个蛋白。通过在微小的纳米孔中一次一个氨基酸地慢慢移动线性化的蛋白，他们能够读出与该蛋白的信息内容有关的电流。他们将他们的概念验证于2021年11月4日在线发表在Science期刊上，论文标题为“Multiple rereads of single proteins at single–amino acid resolution using nanopores”。这种新的单分子肽读取器标志着蛋白鉴定的突破，并为单分子蛋白测序和对单细胞内的蛋白进行编目开辟了道路。https://t.cn/A6xAWLUz
