About this Site (last update: August 9th, 2016)

This version of "Theory and History of Ontology" can also be downloaded as an ebook that can be read offline, stored on a pen drive, sent to a friend by e-mail, etc.

Pages can be read in sequence, starting from the beginning or end of the website, or by consulting the table of contents at the beginning (menu "Contents"), the detailed indexes at the end (menu "Last"), or the chapter index (menu "Section"); a "Search" option is also available.

I will update the e-book every time that the main website will change: see the page "What's New on This Site" for the more recent updates.

The e-book version does not contain the Essays in PDF format (that can be downloaded separately: see the Index of PDF Essays) and the external links that are available on the main version.
