Consider placing a link to this periodic table on your web site. Links help more people find the site as well as increase its ranking in search engines. Please don't place it in a slew of dozens of links to periodic tables. This isn't 1996 and if your visitors want a list of links to periodic tables, they'll visit Google. Exercise your editorial judgement as a webmaster and send them to the resource you believe is best.
Please only link to the main site. This gives your visitors the opportunity to choose whether they'd prefer a certain PDF paper size, image, or the full interactive experience. If you insist on linking to the image or PDF, do not copy it to your server. Hotlink it. You have my permission.
