The Cactaceae, Vol. 1 & Vol. 2
N.L. Britton & J.N. Rose
The Carnegie Institution

In 2006, Daniel Schweich began to reproduce in electronic format the four volumes of the book The Cactaceae issued from 1919 to 1923 by the Carnegie Institution. This is an independent project by Mr. Schweich, and the PDFs produced are entirely his effort. The Carnegie Institution's contribution has been limited to providing server space for the resulting PDFs.

Because scanning books and then interpreting and reformatting text is labor-intensive and imperfect work, mistakes may have been introduced, and thus

the Carnegie Institution and Daniel Schweich are not responsible for the content of or any errors in these files.

However, anybody who finds errors or misprints or wants to comment on the files is welcome. You may contact Daniel Schweich at

Please send e-mail only if really necessary!

Restrictions:

• The files can be distributed for free only.
• You cannot modify the files.
• Any distribution of the files must include this page.

Further details:

• Use Acrobat Reader 6 at least.
• A special layer (“comments”) can be activated (and hidden; see Acrobat Reader help); it shows some comments and corrections. If you use a Reader version older than 6, this layer should be always visible. Avoid using a version older than 5!

There are two PDF files per volume:

• An image file (designated with the suffix “_O”) composed of  scans of the original book for use as a direct  depiction. Because it is an image, you cannot use searching tools to find what you need.
• A text file  that has been “electronically optically recognized” and then reformatted so it may be searched by any word or symbol.
